Sheng Xiaobai was unable to attend the Sheng Family Heirloom Ceremony because he fell into a trap set by his cousin. His uncle Sheng Dongfeng and his father Sheng Nanfeng had a disagreement over the distribution of the family property, and finally decided to determine the distribution of the property by winning or losing in mahjong. After a fierce mahjong competition, Sheng Dongfeng lost the game, and finally even the original heir son Sheng Xiaobai was expelled from the house. Sheng Xiaobai, who had no place to live outside, vowed to take back everything he had lost. In an accident, Sheng Xiaobai met the landlady Shen Wuque, and followed her back to a mysterious "pig cage village" Wulianzhuang. Here, he met many mahjong masters and practiced card skills with them. Later, with the help of Teacher Sun, Sheng Xiaobai's card skills improved by leaps and bounds, and his personality gradually changed from arrogant to kind and humble. In the midst of laughter, Sheng Xiaobai and Shen Wuque also developed a long-lost affection. In the end, Sheng Xiaobai and his uncle Sheng Nanfeng challenged and successfully took back everything that belonged to him.
