A number of bored and gambling-prone students started a gambling game in their dormitory.,As Zhang Fan grew older, he learned that this was a cheating method in gambling. When he was bored, Zhang Fan would often hold cards in his hand and flip them over and over again.,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."。
