There is a beggar gang in Beijing, which is called "gangsters". The leader is Mr. Niu, and everyone who sees him has to give him three points.

This time, the beggar gang smashed Sun Dou's juice stand because Master Niu didn't pay the filial piety fee for his birthday. Sun Liu, the son of Sun Douzhi, is a bloody man. He wants to fight a tough battle with Niu Daxia. Sun Liu took a fancy to his daughter Li around his neck. Both of them have this feeling in their hearts, but they just don't say it. Liu, the owner of a barbecue shop, took a fancy to Li and exchanged 60 yuan for Li to make a canteen. Sun Liu's selling house is not worth 60 yuan. The shopkeeper of Gu Men Restaurant asked Sun Liu to find Master Niu and join the Beggars' Sect. Without much effort, Mr. Niu scared away all the diners in Liu's shopkeeper barbecue shop. Liu Shao, the shopkeeper, obediently surrendered the deed of sale and won back the business. When Sun Liu became a "gangster", his father kicked him out of the house, and Li Wobo didn't want to marry his daughter. Shu Xian became a nun. Gu shopkeeper and Liu shopkeeper were fighting in the dark, and Mr. Niu betrayed Sun Liu at a critical moment. Sun Liu made up her mind to take the dragon whip from Mr Niu. Mr. Niu was swept out of the house by his ancestors, and Sun Liu was in charge of the dragon whip, and he became the head of the "gangsters". The first thing he did was smash the Liu's barbecue shop. Sun Douzhi broke off the father-son relationship with Sun Liu, who consciously did not deserve to marry Shu Xian. Sun Liu simply found four girls who were female "gangsters" under her grandparents. Gu shopkeeper took the opportunity to bargain and bought the barbecue shop, and also framed Sun Liu. Sun Liu was accused of killing Master Niu and was sentenced to death. Four girls decided to avenge Sun Liu. At the wedding banquet of Gu shopkeeper's 50th birthday, there was a loud noise, and Gu shopkeeper and barbecue shop were all reduced to ashes.
