最近，某市不少小区安装了智能快递柜。居民网购之后，快递员把包裹放进柜子里，系统马上发出一条短信，凭密码随时可以取出，二十四小时之内不收费。调查显示，八成以上的居民认为这样取件更自由，不必在家等快递员；不过一些老人觉得操作太复杂，希望得到帮助。

Recently, many neighborhoods in a certain city have installed smart parcel lockers. After residents shop online, the courier places the parcel into a locker, and the system immediately sends a text message; with the password you can take the parcel out at any time, free of charge within twenty-four hours. Surveys show that over eighty percent of residents think collecting parcels this way is freer, since they no longer have to wait at home for the courier; however, some elderly people find the operation too complicated and wish for help.

某科技公司最近推出了一款专为老人设计的智能手环。它能记录使用者每天的步行数量和睡眠质量，还能在老人摔倒的时候，自动向家人发送位置信息。试用半年来，不少子女反馈，父母戴上之后，自己心里踏实多了。专家同时提醒，设备只能起到辅助作用，经常回家看望父母，才是老人最需要的陪伴。

A certain technology company recently launched a smart wristband designed especially for the elderly. It can record the user's daily step count and sleep quality, and when an old person falls, it automatically sends their location to family members. In the six months of trial use, quite a few adult children gave feedback that after their parents put it on, they felt much more at ease. Experts also remind us that such a device can only play a supporting role; frequently coming home to visit one's parents is still the companionship they need most.

近日，两辆无人驾驶的小型公交车在某大学校园里开始试运行。车厢里没有司机，车辆遇到行人时会自动减速停车，师生用手机扫码即可免费乘坐。项目负责人介绍说，试运行阶段，每辆车上都配有一名技术人员，以便突发情况出现时能够立即处理。

Recently two small driverless buses began trial operation on a university campus. There is no driver in the carriage; when the vehicle meets pedestrians it automatically slows down and stops, and students and teachers scan a code with their phones to ride for free. The person in charge of the project explained that during the trial stage each bus carries one technician, so that sudden situations can be dealt with immediately.

过去，电力工人检查山区的高压线路，需要翻过一座又一座山，走上好几天，不仅辛苦，而且危险。如今，这项工作大部分由无人机来完成：它沿着电线飞行、拍摄，再把画面实时传回指挥中心，半天就能完成任务。工作人员表示，新技术不但提高了效率，也明显降低了发生事故的可能。

In the past, electrical workers inspecting high-voltage lines in mountain areas had to climb one mountain after another and walk for days on end, exhausting and dangerous work. Nowadays most of this job is done by drones: they fly along the power lines taking photographs and transmit the images back to the command center in real time, finishing the task in half a day. Workers say the new technology has not only raised efficiency but also clearly reduced the possibility of accidents.

某连锁超市最近开通了刷脸支付：结账时，顾客只要对着摄像设备看一下，几秒钟就能完成付款，不必再拿出手机或钱包。不过，也有一些消费者担心自己的面部信息会被过度收集。对此，商家回答说，顾客有权选择用二维码付款，个人的面部数据不会被保存，更不会被交给第三方。

A chain of supermarkets recently introduced face-scanning payment: at checkout, customers simply look at a camera device for a few seconds and the payment is completed, without taking out a phone or wallet. Some consumers, however, worry that their facial information will be collected excessively. In response, the retailer says customers are entitled to choose QR-code payment instead, and personal facial data will neither be stored nor handed over to third parties.

一项针对两千个家庭的最新调查显示，超过一半的家庭已经在使用语音助手，让它播放音乐、报告天气或者控制家中的灯光。使用频率最高的是年轻父母，孩子们也很喜欢跟它聊天。研究人员同时指出，这类设备虽然方便，用户也应当注意保护个人隐私，敏感的信息尽量少告诉它。

The latest survey of two thousand families shows that more than half already use voice assistants, having them play music, report the weather, or control the lights at home. Usage is highest among young parents, and children also enjoy chatting with it. Researchers point out at the same time that although such devices are convenient, users ought to protect their personal privacy and tell the device as little sensitive information as possible.

如今在许多商场和餐厅，顾客扫描二维码就能租到一台共享充电宝，用完之后在任何一台机器上归还即可，费用按小时计算。这项服务解决了手机突然没电带来的麻烦，尤其受到年轻人的欢迎。不过也有用户投诉说，个别地方归还困难，容易产生多余的费用。相关企业回应，将增加更多网点并改进管理。

Nowadays in many shopping malls and restaurants customers scan a QR code to rent a shared power bank, and after using it simply return it at any machine, with the fee calculated by the hour. This service solves the trouble of a phone suddenly running out of power, and is especially popular among young people. Some users complain, however, that returning one is difficult in certain places, which easily produces unnecessary charges. The companies concerned respond that they will add more branches and improve management.

某市把三个老城区的普通水表换成了智能水表。新水表每十五分钟自动读一次数，数据直接传到管理系统，查表员不必再一家一家上门；住户家中如果漏水，系统会马上向手机发送提醒。换表半年来，已帮助二十多户人家及时发现管道漏水，避免了更大损失。交费方式不变，不会用手机的老人仍然可以到营业网点交费。

A certain city replaced the ordinary water meters in three old districts with smart meters. The new meters read themselves automatically every fifteen minutes and send the data straight to the management system, so meter readers no longer have to call door to door; if water is leaking in a household, the system immediately sends an alert to the phone. In the half year since the swap, leaks in the pipes of more than twenty households have been found in time, avoiding greater loss. The payment method is unchanged: elderly people who cannot use smartphones can still pay at service branches.

近年来，网络购物发展迅速，送货环节的人力成本却越来越高。为了解决这个问题，上个月，某市批准一家企业在三条固定路线上开展无人驾驶送货车的试运行。这种车的车顶装有多个摄像镜头，能够识别红绿灯，遇到行人会自动减速，车速被限制在每小时二十公里以内。运行期间，企业为每辆车安排了一名远程安全员：一旦系统发现异常，安全员可以立即接管车辆，保证路上行人和车辆的安全。首批投入使用的十辆送货车主要服务于两个大型社区，居民在楼下扫描二维码，就能打开车厢取出自己的包裹。企业负责人表示，开展无人配送并不是为了取代快递员，而是把他们从重复的搬运工作中解放出来，去做更需要与人交流的工作。有关部门也强调，试运行收集到的数据，将为今后制定行业规则提供重要依据。

In recent years online shopping has developed rapidly, yet the labour cost of the delivery stage keeps rising. To solve this problem, last month a certain city approved a company to begin trial operation of driverless delivery vans on three fixed routes. The roof of each van carries several camera lenses; it can recognize traffic lights, slows down automatically when meeting pedestrians, and its speed is limited to twenty kilometres per hour. During operation the company assigns one remote safety officer to every vehicle: once the system detects anything abnormal, the officer can take over the van immediately, keeping pedestrians and other vehicles safe. The first ten delivery vans put into service mainly cover two large neighborhoods; residents scan a QR code downstairs and can open the carriage and take out their parcels. The head of the company said the aim of driverless delivery is not to replace couriers but to free them from repetitive carrying work so they can do jobs that require more human contact. The department concerned also stressed that the data collected during the trial will provide an important basis for drawing up industry rules in the future.

每到节假日，不少城市都会举办大型无人机表演：上千架小飞机同时升空，在夜空中变换出各种各样的图案，吸引大量市民前来观看。与传统的烟花相比，无人机表演非常安静，也不会产生烟雾，对环境更加友好；而且图案可以通过程序提前设计，随时更换，表现力更强。一家表演公司的技术负责人介绍，一场成功的表演，离不开事先精确的设计：每一架飞机的位置、速度和灯光颜色都被写入程序，飞行时由地面的电脑统一控制，位置误差只有几厘米。当然，这类表演对天气的要求也很高，一旦遇到大风或者下雨，活动往往只能取消。业内人士预计，随着成本的不断下降，以后会有更多的中小城市在自己的夜空中看到这样精彩的表演。

On public holidays many cities stage large-scale drone shows: more than a thousand small aircraft rise into the sky together, forming all kinds of patterns in the night sky and drawing large crowds of residents. Compared with traditional fireworks, drone shows are very quiet and produce no smoke and are friendlier to the environment; moreover the patterns can be designed in advance through a program and changed at any time, making them far more expressive. The technical director of a performance company explained that a successful show depends on precise advance design: the position, speed and light color of every aircraft are written into the program, and during flight they are controlled uniformly by ground computers, with positional error of only a few centimetres. Of course such shows demand a great deal from the weather: when strong wind or rain arrives, the event usually has to be cancelled. People in the industry predict that as costs keep falling, more small and medium-sized cities will see such wonderful performances in their night skies.

随着移动支付的普及，很多老年人发现，出门买菜、看病挂号、乘坐公交车，都离不开智能手机，这让他们感到非常不便。为此，某市的多家社区开设了免费的手机课，由大学生志愿者当老师，从开机、连接网络教起，一直到扫码付款、视频通话，内容十分实用。每期课程一共八讲，每周上两次，时间都安排在下午，方便老人出门。志愿者刘婷说，教老人最大的困难不是他们学得慢，而是很多人不敢按、怕把手机弄坏，所以课程特意放慢了进度，每个步骤都反复练习，学员还可以领到一本印着大字的操作手册。三个月下来，两百多位老人完成了全部课程，其中七成以上已经能够独立扫码购物。社区负责人表示，技术进步不应该丢下任何一位老人，帮助他们跟上时代，是全社会共同的责任。除了手机课，社区还计划开设网上挂号和打车软件的专题讲座。

With the spread of mobile payment many elderly people have found that grocery shopping, hospital registration and bus rides all depend on smartphones, which leaves them greatly inconvenienced. To help, several communities in a certain city opened free smartphone classes taught by student volunteers, starting from switching on the device and connecting to the network, all the way to QR-code payment and video calls, thoroughly practical content. Each course runs eight sessions, twice a week, scheduled in the afternoon so it is easy for seniors to come out. Volunteer Liu Ting said the biggest difficulty in teaching the elderly is not that they learn slowly but that many dare not press anything, afraid of breaking the phone; so the course deliberately slows the pace, practices every step repeatedly, and learners receive a manual printed in large characters. Three months on, more than two hundred elderly people completed the whole course, over seventy percent of whom can already shop by scanning a code independently. The community director said technological progress must not leave a single old person behind; helping them keep up with the times is the shared responsibility of the whole society. Besides phone classes, the communities also plan special lectures on online hospital registration and ride-hailing apps.

走进某电商企业的自动化仓库，人们几乎看不到工人的身影：装满商品的货架自己在轨道上移动，机器手臂把商品放进纸箱，打包、贴单、分类整理全部由设备完成，只有少数工程师坐在电脑前，看着屏幕上的数据。负责人算了一笔账：传统仓库处理一万件商品，大约需要三十个人工；而在这里，五六名技术人员就足够了，出错率也从千分之五降到了万分之一以下。不过，高效率的背后是巨大的投入，这套系统的建设成本超过一亿元，后期的维护费用同样昂贵，因此目前只在订单量特别大的仓库中使用。专家认为，自动化并不等于让工人失业，新的岗位正在不断出现，比如设备维修员、数据整理员、流程设计师——这些都是五年前还不存在的职业。

Stepping into the automated warehouse of an e-commerce company, one sees hardly any workers: shelves loaded with goods glide along tracks on their own, robot arms place products into cardboard boxes, and packing, labelling and sorting are all done by machines; only a handful of engineers sit before computers watching the data on their screens. The manager did the math: a traditional warehouse needs about thirty workers to process ten thousand items, whereas here five or six technicians are enough, and the error rate has fallen from five in a thousand to below one in ten thousand. Behind the high efficiency, however, lies enormous investment: the system costs more than a hundred million yuan to build, and maintenance is equally expensive, so it is currently used only in warehouses with very high order volumes. Experts believe automation does not equal putting workers out of work: new positions keep appearing, such as equipment maintainer, data organizer and process designer: occupations that did not exist five years ago.

戴上手表睡觉，早上醒来先查看昨夜深睡的时间有多长，已经成为不少年轻人的新习惯。电商平台的数据显示，最近三年，各类睡眠设备的销量增长了三倍，价格从几百元到几千元不等。这类设备通过测量心跳、身体活动等指标来估算用户的睡眠质量，并给出相应的改善建议。一些产品还能把睡眠数据分享给家人，让远在外地的子女了解父母的休息情况。医生提醒，普通消费级设备的参考价值有限，数据存在明显的误差，长期失眠的人应当到医院检查治疗，而不是完全相信手环给出的分数。心理学研究者还发现了一个新现象：一些人过分关注睡眠数据，反而产生了新的焦虑，越测越睡不着。专家建议，按时睡觉起床、睡前少看手机，比任何设备都更有效。

Going to sleep wearing a watch and checking upon waking how long last night's deep sleep lasted has become a new habit for quite a few young people. E-commerce platform figures show that sales of all kinds of sleep devices have tripled in the past three years, priced anywhere from a few hundred to several thousand yuan. Such devices estimate a user's sleep quality by measuring heartbeat, bodily movement and other indicators, and offer corresponding improvement suggestions. Some products can also share sleep data with family members, letting adult children far away know how their parents are resting. Doctors warn that ordinary consumer-grade devices have limited reference value and their data carry obvious errors; people who suffer long-term insomnia should go to hospital for examination and treatment instead of entirely trusting the score the band gives them. Psychology researchers have also noticed a new phenomenon: some people pay excessive attention to sleep data and develop fresh anxiety as a result: the more they measure, the less they can fall asleep. Experts advise that going to bed and getting up on schedule and looking at your phone less before sleep work better than any device.

赵磊工程师，听说你们团队用大数据来调整全市的红绿灯，这套系统到底是怎么工作的？

Zhào Lěi gōngchéngshī, tīngshuō nǐmen tuánduì yòng dà shùjù lái tiáozhěng quán shì de hónglǜdēng, zhè tào xìtǒng dàodǐ shì zěnme gōngzuò de?

Engineer Zhao Lei, we hear your team uses big data to adjust the whole city's traffic lights. How exactly does this system work?

简单地说，城市的主干道就像人的血管，我们的系统负责让它保持畅通。路口的摄像设备和安装在路面上的检测装置，每分钟都在向数据中心发送车流信息；系统根据这些数据，计算出下一个时段每个方向需要多长的绿灯时间，然后自动调整信号灯。过去红灯的长短是固定不变的，现在它每一分钟都在变化。我们在二十个路口试了一年，司机平均等待的时间下降了百分之十五左右。

Jiǎndān de shuō, chéngshì de zhǔgāndào jiù xiàng rén de xuèguǎn, wǒmen de xìtǒng fùzé ràng tā bǎochí chàngtōng. Lùkǒu de shèxiàng shèbèi hé ānzhuāng zài lùmiàn shang de jiǎncè zhuāngzhì, měi fēn zhōng dōu zài xiàng shùjù zhòngxīn fāsòng chēliú xìnxī; xìtǒng gēnjù zhèxiē shùjù, jìsuàn chū xià yí ge shíduàn měi ge fāngxiàng xūyào duō cháng de lǜdēng shíjiān, ránhòu zìdòng tiáozhěng xìnhàodēng. Guòqù hóngdēng de chángduǎn shì gùdìng bú biàn de, xiànzài tā měi yì fēn zhōng dōu zài biànhuà. Wǒmen zài èrshí ge lùkǒu shì le yì nián, sījī píngjūn děngdài de shíjiān xiàjiàng le bǎi fēn zhī shíwǔ zuǒyòu.

Simply put, a city's main roads are like blood vessels, and our system keeps them flowing smoothly. Cameras at intersections and detectors installed under the road surface send traffic-flow information to the data center every minute; based on this data the system calculates how long each direction's green light should be in the coming interval, then adjusts the signals automatically. In the past the length of a red light never changed; now it changes every minute. We trialled it at twenty intersections for a year, and drivers' average waiting time fell by about fifteen percent.

效果听起来很明显。能不能举一个具体的例子，说说哪条路改善得最多？

Xiàoguǒ tīng qǐlái hěn míngxiǎn. Néng bù néng jǔ yí ge jùtǐ de lìzi, shuō shuo nǎ tiáo lù gǎishàn de zuì duō?

The results sound obvious. Could you give a concrete example of which road improved the most?

最典型的是火车站旁边那条路。早上进城的车特别多，晚上出城的车特别多，而以前信号灯一天只按同一套时间表工作，结果两个高峰都堵得厉害。我们为系统设计了早晚分开的模式：早上一边绿灯长，晚上另一边绿灯长，再把附近几个路口的信号连接起来，让车流一路碰到的都是绿灯。现在，这条路的排队长度缩短了将近一半。

Zuì diǎnxíng de shì huǒchēzhàn pángbiān nà tiáo lù. Zǎoshang jìn chéng de chē tèbié duō, wǎnshang chū chéng de chē tèbié duō, ér yǐqián xìnhàodēng yì tiān zhǐ àn tóng yí tào shíjiān biǎo gōngzuò, jiéguǒ liǎng ge gāofēng dōu dǔ de lìhai.

Xiànzài, zhè tiáo lù de páiduì chángdù suōduǎn le jiāngjìn yí bàn.

The most typical case is the road beside the railway station. Inbound traffic is heavy in the morning and outbound heavy in the evening, yet the signals used to follow a single timetable all day, so both peaks jammed badly. We designed a morning-evening split mode for the system: mornings one direction gets a long green, evenings the other does, and the signals of nearby intersections are linked so traffic meets green lights all the way. Now queues on that road have shrunk by nearly half.

有些司机一开始可能不相信电脑调出来的灯，你们是怎么获得大家信任的？

Yǒuxiē sījī yì kāishǐ kěnéng bù xiāngxìn diànnǎo tiáo chūlái de dēng, nǐmen shì zěnme huòdé dàjiā xìnrèn de?

Some drivers may not have trusted computer-adjusted lights at first. How did you gain everyone's trust?

这个问题问得非常好。刚开始确实有人在网上留言批评。我们做了两件事：一是把调整前后的数据全部公开，欢迎任何人查询；二是在地图软件里显示信号灯的变化，司机一看，等待时间真的变短了。三个月以后，批评的声音几乎消失了。现在我们每天都能收到市民的建议，其中不少已经被采纳。

Zhège wèntí wèn de fēicháng hǎo. Gāng kāishǐ quèshí yǒu rén zài wǎngshang liúyán pīpíng. Wǒmen zuò le liǎng jiàn shì: yī shì bǎ tiáozhěng qián hòu de shùjù quánbù gōngkāi, huānyíng rènhé rén cháxún; èr shì zài dìtú ruǎnjiàn li xiǎnshì xìnhàodēng de biànhuà, sījī yí kàn, děngdài shíjiān zhēn de biàn duǎn le.

That's an excellent question. At the start some people did leave critical comments online. We did two things: first, we made all the before-and-after data public, open to anyone who wants to check; second, map apps began showing the signal changes, and once drivers saw waiting times really getting shorter, the criticism had almost vanished three months on. Now we receive citizens' suggestions every day, and quite a few have been adopted.

最后，您能透露一下团队下一步的计划吗？

Zuìhòu, nín néng tòulù yíxià tuánduì xià yí bù de jìhuà ma?

Finally, can you reveal the team's plan for the next step?

我们正在把这套系统推广到另外两个城区，同时也在尝试用类似的方法，为公交车和救护车留出专用车道。希望有一天，“堵车”在这座城市会成为一个历史名词。

Wǒmen zhèngzài bǎ zhè tào xìtǒng tuīguǎng dào lìngwài liǎng ge chéngqū, tóngshí yě zài chángshì yòng lèisì de fāngfǎ, wèi gōngjiāo chē hé jiùhùchē liú chū zhuānyòng chēdào. Xīwàng yǒu yì tiān, 'dǔchē' zài zhè zuò chéngshì huì chéngwéi yí ge lìshǐ míngcí.

We are extending the system to two more districts and trying similar methods to set aside dedicated lanes for buses and ambulances. We hope that one day 'traffic jam' will become a historical term in this city.

林经理，您负责的居家适老化智能改造项目，具体会给老人的家带来哪些变化？

Lín jīnglǐ, nín fùzé de jūjiā shì lǎohuà zhìnéng gǎizào xiàngmù, jùtǐ huì gěi lǎorén de jiā dàilái nǎxiē biànhuà?

Manager Lin, what concrete changes will your age-friendly smart home renovation project bring to seniors' homes?

我们主要做三件事。首先是安全：厨房安装燃气报警器，发现漏气会自动切断燃气供应；卫生间的地面换成防滑材料，墙上加装扶手。其次是方便：电灯可以用说话的方式打开和关上，老人不用来回走动。最后是求救：卧室和卫生间装上紧急呼叫器，老人一按，社区服务站和他子女的手机就会同时收到危险通知。去年我们改造了一百户人家，今年这个数字翻了一番。另外，我们还会给每一位老人配一张紧急联系卡，放在家中显眼的位置。

Wǒmen zhǔyào zuò sān jiàn shì. Shǒuxiān shì ānquán: chúfáng ānzhuāng ránqì bàojǐngqì, fāxiàn lòuqì huì zìdòng qiēduàn ránqì gōngyìng; wèishēngjiān de dìmiàn huàn chéng fánghuá cáiliào, qiáng shang jiāzhuāng fúshou.

We mainly do three things. First, safety: gas alarms in the kitchen cut the gas supply automatically when a leak is detected; bathroom floors are replaced with anti-slip material and handrails added to the walls. Second, convenience: the lights answer voice commands, switching on and off, so seniors need not walk back and forth. Third, calling for help: emergency buttons in the bedroom and bathroom: one press sends a danger alert simultaneously to the community service station and the children's phones. Last year we renovated one hundred homes; this year the figure has doubled. In addition, every senior receives an emergency contact card, placed in the most visible spot at home.

改造一套房子大概要花多少钱？这笔钱都由老人自己承担吗？

Gǎizào yí tào fángzi dàgài yào huā duōshao qián? Zhè bǐ qián dōu yóu lǎorén zìjǐ chéngdān ma?

About how much does renovating one apartment cost? Do the elderly bear the cost themselves?

基础套餐大约八千元，包括刚才说的那些安全设备；如果想要更多功能，比如能打电话的床头屏幕，费用还会增加。好消息是，政府现在有补贴，符合条件的家庭最高可以少付一半的费用。我们的原则是自己愿意少赚一点，也要让退休金不高的老人用得起。目前，全市已经有六个区把这类改造列进了为老服务的项目清单。

Jīchǔ tàocān dàyuē bā qiān yuán, bāokuò gāngcái shuō de nàxiē ānquán shèbèi; rúguǒ xiǎng yào gèng duō gōngnéng, bǐrú néng dǎ diànhuà de chuángtóu píngmù, fèiyòng hái huì zēngjiā. Hǎo xiāoxi shì, zhèngfǔ xiànzài yǒu bǔtiē, fúhé tiáojiàn de jiātíng zuìgāo kěyǐ shǎo fù yí bàn de fèiyòng. Wǒmen de yuánzé shì zìjǐ yuànyì shǎo zhuàn yìdiǎn, yě yào ràng tuìxiūjīn bù gāo de lǎorén yòng de qǐ. Mùqián, quán shì yǐjīng yǒu liù ge qū bǎ zhè lèi gǎizào liè jìn le wèi lǎo fúwù de xiàngmù qīngdān.

The basic package costs about eight thousand yuan and covers the safety devices just mentioned; extra functions such as a bedside screen that makes calls cost more. The good news is the government now offers subsidies: qualifying families pay up to half less. Our principle is to accept earning less ourselves rather than price out seniors on modest pensions. So far six districts citywide have put such renovations on their elderly-service project lists.

有人觉得，机器再聪明也不能代替人去照顾老人，您怎么看这种观点？

Yǒu rén juéde, jīqì zài cōngming yě bù néng dàitì rén qù zhàogù lǎorén, nín zěnme kàn zhè zhǒng guāndiǎn?

Some people feel that no matter how clever machines get, they cannot replace human care for the elderly. What's your view?

我完全同意前半句。设备代替不了子女的探望，也代替不了邻居之间的关心，它做的只是争取时间——老人摔倒之后几分钟内就有人知道，这几分钟也许就是生和死的差别。所以我们总是跟客户说，智能设备是帮手，不是亲人。另外在隐私方面我们也特别注意，老人可以选择不在卧室安装任何摄像设备。

Wǒ wánquán tóngyì qián bàn jù. Shèbèi dàitì bù liǎo zǐnǚ de tànwàng, yě dàitì bù liǎo línjū zhījiān de guānxīn, tā zuò de zhǐ shì zhēngqǔ shíjiān — lǎorén shuāidǎo zhīhòu jǐ fēn zhōng nèi jiù yǒu rén zhīdao, zhè jǐ fēn zhōng yěxǔ jiù shì shēng hé sǐ de chābié. Suǒyǐ wǒmen zǒng shì gēn kèhù shuō, zhìnéng shèbèi shì bāngshǒu, bú shì qīnrén. Lìngwài zài yǐnsī fāngmiàn wǒmen yě tèbié zhùyì, lǎorén kěyǐ xuǎnzé bú zài wòshì ānzhuāng rènhé shèxiàng shèbèi.

I fully agree with the first half. Devices cannot replace children's visits or neighbors' care; what they do is buy time: within minutes of a fall someone knows, and those minutes can be the difference between life and death. So we always tell clients: smart devices are helpers, not family. We're also especially careful about privacy: residents can choose not to install any camera in the bedroom.

最后，对那些还在犹豫要不要改造的老人，您想说点什么？

Zuìhòu, duì nàxiē hái zài yóuyù yào bú yào gǎizào de lǎorén, nín xiǎng shuō diǎn shénme?

Lastly, what would you say to seniors still hesitating about renovation?

我想说，改造不是为了图新鲜，而是为了让日子过得更踏实。大家可以先从最需要的一项做起，比如先装一个紧急呼叫器，觉得好用，再一步一步增加其他设备。

Wǒ xiǎng shuō, gǎizào bú shì wèile tú xīnxiān, ér shì wèile ràng rìzi guò de gèng tāshi. Dàjiā kěyǐ xiān cóng zuì xūyào de yí xiàng zuò qǐ, bǐrú xiān zhuāng yí ge jǐnjí hūjiàoqì, juéde hǎoyòng, zài yí bù yí bù zēngjiā qítā shèbèi.

I'd say renovation is not about seeking novelty but about making daily life more secure. Start with whatever you need most (an emergency button, for instance) and once you find it useful, add other devices step by step.

杨经理，用无人机给山村送包裹，你们当初是怎么想到做这个项目的？

Yáng jīnglǐ, yòng wúrénjī gěi shāncūn sòng bāoguǒ, nǐmen dāngchū shì zěnme xiǎngdào zuò zhège xiàngmù de?

Manager Yang, delivering parcels to mountain villages by drone: how did you come up with this project?

我们公司在山区做过调查：有一个乡离县城只有四十公里，可是山路要绕三个小时，快递往往一个星期才送一次，药品、证件这些急用的东西根本等不起。我们就想，山里两点的直线距离其实很近，为什么不从天上走呢？前年十月，第一条航线正式开通，二十五分钟就能从县城飞到那个乡。

Wǒmen gōngsī zài shānqū zuò guò diàochá: yǒu yí ge xiāng lí xiànchéng zhǐ yǒu sìshí gōnglǐ, kěshì shānlù yào rào sān ge xiǎoshí, kuàidì wǎngwǎng yí ge xīngqī cái sòng yí cì, yàopǐn, zhèngjiàn zhèxiē jí yòng de dōngxi gēnběn děng bu qǐ. Wǒmen jiù xiǎng, shān li liǎng diǎn de zhíxiàn jùlí qíshí hěn jìn, wèishénme bù cóng tiānshang zǒu ne? Qián nián shí yuè, dì yì tiáo hángxiàn zhèngshì kāitōng, èrshíwǔ fēn zhōng jiù néng cóng xiànchéng fēi dào nàge xiāng.

Our company surveyed mountain areas: one township lies only forty kilometres from the county seat, yet the winding mountain road takes three hours, and parcels often arrive just once a week; urgent items like medicine and documents simply cannot wait that long. We thought: as the crow flies the distance is short, so why not travel through the sky? In October two years ago the first route officially opened; twenty-five minutes gets you from the county seat to that township.

把包裹交给一台无人机器运送，村民放心吗？飞行安全又是怎么保证的？

Bǎ bāoguǒ jiāo gěi yì tái wúrén jīqì yùnsòng, cūnmín fàngxīn ma? Fēixíng ānquán yòu shì zěnme bǎozhèng de?

Handing parcels to unmanned machines: were villagers reassured? And how is flight safety guaranteed?

刚开始，大家好奇多于信任，常常站在下面看热闹。为了让乡亲们安心，我们定了三条规矩：首先，每架飞机都沿着固定的航线飞行，高度比山头还高出几十米，绝不经过学校和居民区；其次，包裹挂上小型的降落伞，万一出现意外，也能慢慢落下来；另外，天气不好坚决停飞，风速一超过标准，当天的任务全部取消。现在村民凭密码在投放点取件。

Gāng kāishǐ, dàjiā hàoqí duō yú xìnrèn, chángcháng zhàn zài xiàmian kàn rènao. Wèile ràng xiāngqīn men ānxīn, wǒmen dìng le sān tiáo guīju: shǒuxiān, měi jià fēijī dōu yánzhe gùdìng de hángxiàn fēixíng, gāodù bǐ shāntóu hái gāo chū jǐ shí mǐ, juébù jīngguò xuéxiào hé jūmínqū; qícì, bāoguǒ guà shang xiǎoxíng de jiàngluòsǎn, wànyì chūxiàn yìwài, yě néng mànmàn luò xiàlái; lìngwài, tiānqì bù hǎo jiānjué tíngfēi, fēngsù yì chāoguò biāozhǔn, dàngtiān de rènwu quánbù qǔxiāo. Xiànzài cūnmín píng mìmǎ zài tóufàng diǎn qǔ jiàn.

At first curiosity outweighed trust; people gathered below to watch the spectacle. To reassure them we set three rules: every plane flies a fixed route tens of meters above the peaks, never passing over schools or residential areas; parcels carry small parachutes so even in an accident they drift down slowly; and in bad weather we firmly ground the fleet: wind above the limit cancels the day's missions. Villagers now collect parcels with a password at the drop points.

下一步有什么计划？飞行成本比较高的问题怎么解决？

Xià yí bù yǒu shénme jìhuà? Fēixíng chéngběn bǐjiào gāo de wèntí zěnme jiějué?

What's next? And how will you solve the problem of high flight costs?

我们准备再开通五条航线，把附近的乡镇都连接起来。另外也在尝试运送新鲜水果：山里的果子早上摘下来，中午就能摆上县城的市场，农民的收入明显增加了。说实话，每一次飞行的成本现在还是比较高，主要靠政府和企业的合作支撑。但我相信，飞的次数多了，成本自然会降下来，这是一笔值得好好算的账。等到条件成熟了，我们还希望把这项服务推广到更远的村子。

Wǒmen zhǔnbèi zài kāitōng wǔ tiáo hángxiàn, bǎ fùjìn de xiāngzhèn dōu liánjiē qǐlái. Lìngwài yě zài chángshì yùnsòng xīnxiān shuǐguǒ: shān li de guǒzi zǎoshang zhāi xiàlái, zhōngwǔ jiù néng bǎi shàng xiànchéng de shìchǎng, nóngmín de shōurù míngxiǎn zēngjiā le. Shuō shíhuà, měi yí cì fēixíng de chéngběn xiànzài hái shì bǐjiào gāo, zhǔyào kào zhèngfǔ hé qǐyè de hézuò zhīchēng. Dàn wǒ xiāngxìn, fēi de cìshù duō le, chéngběn zìrán huì jiàng xiàlái, zhè shì yì bǐ zhídé hǎohǎo suàn de zhàng. Děng dào tiáojiàn chéngshú le, wǒmen hái xīwàng bǎ zhè xiàng fúwù tuīguǎng dào gèng yuǎn de cūnzi.

We plan to open five more routes linking the nearby townships. We're also trying fresh fruit transport: fruit picked in the morning can be on county-market stalls by noon, and farmers' incomes have clearly risen. Honestly, each flight still costs quite a lot, supported mainly by government-business cooperation. But I believe as flight numbers grow the cost will naturally fall, an equation worth working out. Once conditions mature, we hope to extend the service to even more distant villages.

采访的最后，您还有什么想对山里的乡亲们说的吗？

Cǎifǎng de zuìhòu, nín hái yǒu shénme xiǎng duì shān li de xiāngqīn men shuō de ma?

At the end of this interview, is there anything you would like to say to the villagers?

谢谢他们的信任。没有乡亲们的理解和支持，我们的飞机根本飞不起来。我们会继续努力，让山里山外的联系越来越紧密，也请大家继续给我们提意见。

Xièxie tāmen de xìnrèn. Méiyǒu xiāngqīn men de lǐjiě hé zhīchí, wǒmen de fēijī gēnběn fēi bu qǐlái. Wǒmen huì jìxù nǔlì, ràng shān li shān wài de liánxì yuèláiyuè jǐnmì, yě qǐng dàjiā jìxù gěi wǒmen tí yìjiàn.

Thanks for their trust. Without the villagers' understanding and support our planes could never take off. We will keep working so that connections across the mountains grow ever closer, and please keep sending us suggestions.
