Zhang Fan's parents were both laid-off workers, and he had a younger sister who was 7 years younger than him. Their family life was inevitably difficult financially. When he received his university admission notice that year, he only managed to scrape together his tuition fees with the help of relatives and friends.,Room 504 was a gathering place for gamblers. When Zhang Fan knocked on the door, a voice inside shouted at him, "Dealer, you've been slacking off lately. If you don't come soon, I'll starve to death. Hurry up, two packs of braised meat and two eggs.",More than four years as a street vendor has allowed Zhang Fan to experience the harshness of society prematurely. Almost every time he speaks, there is a careful smile on his face, a sad pre-emptive laugh!。
