Mr. Hou, who makes good money, came up with another way to make money. He organized a weight-loss tour group to let the fat man lose weight when traveling to the Three Gorges, killing two birds with one stone. He made Jingjing, his obsessed tiger trainer, the leader. There are many fat people now. To lose weight, there is a fat lady in Hong Kong. She has been spoiled since childhood and always eats snacks. Mr. Liang, who is rich, has plenty of money, but he is worried about being fat; There is a chubby little treasure who still wets the bed when he is so big; Mr. Lin, the thin monkey, is mixed in the fat pile. He was put in a box by his fat wife and taken to the boat. These people have their own ways, and no one will buy anyone's account, which makes the weight loss group fidgety. Jingjing works hard. She forced the fat man to lose weight by taming the tiger, which made them all complain. Mr. Hou doesn't care about the fat man at all, but he is bent on pleasing Jingjing. As soon as he arrived at his destination, he wanted to fly away with Jingjing. Just when everyone was in uproar, another "qigong master" came. She openly said that lectures on merit could help her lose weight, but secretly she robbed the fat man of a lot of money. Until the public security personnel took the female liar away. Through the facts, Jingjing finally saw through Mr. Hou's deception. She teamed up with the fat man and gave Manager Hou a hard time. Mr. Hou accidentally almost burned himself to death. Fortunately, the fat man Qi Xin saved him, which made Mr. Hou, who only wanted to harm others and make money, have a conscience. In the end, all the fat people lost weight more or less, except the fat lady who kept eating.
