If you have ever ordered a cup of hot coffee or tea to be delivered（遞送） in the winter，it was probably cold when it arrived because of the freezing weather.Wouldn't it be great if，instead of arriving from a delivery person，you received it in half the time from an unmanned aerial vehicle （UAV） commonly known as a drone（無(wú)人機(jī)）—right outside your window and was still hot？It's all happening now，as several Chinese cities，including Shenzhen in Guangdong province，Shanghai and Hangzhou in Zhejiang province，began using UAVs for deliveries.Technology is serving people faster than expected.
    Meituan was among the first group to start UAV trials in the city."Technologies like UAVs are expected to play a greater role within a three-kilometer serving area，"said Mao Yinian，head of Meituan's UAV business.According to Mao， the drone can fly at a height of less than 120 meters at a flight speed of 10 meters per second（每秒）.It can carry a box of 3 kg and stay in air for up to20 minutes."In the next five to 10 years，the cost of unmanned deliveries will be the same to that of human deliveries，and the user experience brought by UAVs will be greatly improved，"he said.
    In order to improve the experience of delivery，Meituan started the study of the UAV delivery service in 2017.In 2021，Meituan completed its first drone delivery in Shenzhen.As of December2022，Meituan's drone delivery service has landed in Shenzhen and Shanghai，covering 18 office buildings，serving about 20，000 homes，and completing more than 120，000 orders.The usual delivery time of Meituan's UAV in 2022 was about 12 minutes.It is nearly 150 percent faster than traditional delivery models，saving users more than 30，000 hours of waiting time.
