Lin Yu, an ordinary delivery boy, comes from a rural area. His family is poor but he is honest, kind and hard-working. He has the ambition to take root in a big city and let his family live a good life. I shuttle through the streets and alleys of the city to deliver food every day. Because I am familiar with the city routes, I occasionally take online taxis to pick up and deliver food to distant places. I often communicate with the online taxi masters and learn about all kinds of people and things.
