A young gangster in the city met an old gangster from the military area. Unexpectedly, they met a man and his wife. I went there and had this kind of operation. The old gangster started to practice and learned the little gangster's routine into his mouth step by step. He didn't want to kill Cheng Yaojin halfway, and the fat in his mouth was about to become someone else's. How should the old gangster deal with it, and where should the little gangster go.
