1 . In Chinese cities, food deliverymen are often seen riding at full speed through busy traffic. They rushed from restaurants to different destinations, even under bad weather conditions.

The article The Food Deliverymen Are Trapped in the App pointed out that on food delivery service platforms, Eleme and Meituan, the time limit and the route for each delivery order is calculated by an algorithm（算法）.But the algorithm doesn't consider real-life situations, such as red lights, speed limits and fully occupied elevators.

The time limit for a delivery order within 2 kilometers is 30 minutes, even shorter in recent years. Delay could mean a fine. So deliverymen rev up, often breaking traffic rules, putting their own lives at risk.

Many people asked the platforms to improve the regulations imposed(强加) on the deliverymen. In response to this demand, Eleme announced it would add a button to the app, which allowed customers to extend the time limits for their orders, and encouraged customers to show more respect for deliverymen. But some people felt that the company was staying away from the problem and changing people’s attention. Some held the view that the company was putting the responsibility on the customers rather than solving the problem itself.

As to delivery delays, solutions are far from enough. As a matter of fact, when a delivery delay happens and the company can’t reach an agreement with the customer on the responsibility, the deliveryman is usually the final one responsible for the delay. The Shanghai Customer Council commented that it was unfair for the deliveryman to be the only side responsible for a delay and problems should be solved between the companies and their employees. Besides, market regulatory departments should stop companies from setting tight schedules for their deliverymen and keep them safe on the roads.
