    With the development of Internet and the increasing needs for taxis, online car-hailing(网约车) is becoming more and more popular in China. Didi is used by most Chinese people, and Uber, Yidao, Shenzhou are also welcomed by passengers.

It’s easy for us to hail a car through certain apps. Open the app, and it will locate(定位) your address. After entering where you are going, the app will help you find the nearest personal car owners or taxi drivers. You can choose different kinds of services on the app. For example, if you choose tailored taxi(专车) service, the car is usually big and new. The driver will open the door for you and offer free water and Wifi. If it rains, an umbrella is usually provided. If you choose “hitch”(顺风车), the car owner nearby can give you a ride according to his own routes(路线). And you should pay him to share the cost. Of course, it costs less than hailing a taxi. No matter what kinds of service you choose, you don’t have to pay by cash. You can pay by Wechat or Alipay.

Although car-hailing has a lot of advantages, some people are still worried about its safety. Earlier last month, a young girl passenger was killed by a “hitch” driver on her way home in Zhengzhou. It’s not the first time the passenger gets hurt while using Didi. This news quickly became hot and many people discuss it online now. Some people doubt if it is illegal(合法的) for personal cars to work as taxis in China. Others think young girls should think twice while choosing “hitch”, especially at night. But most people think government must make some strict rules for car-hailing services, including restrictions(限制) about drivers’ hukou, age, job experiences and car age. “We need to listen to the suggestions from society, and perfect it in practice.” said some experts, “What is for sure is that the competition in the future lies in safety and service. Whoever can provide better user experience will win.”
