Under the Gate of Zhengyang consists of the stories of Han Chunming, Su Meng and Cheng Jianjun. At the beginning, Su Meng entered the Cultural Palace, went to college, and entered the unit, becoming a "favored son of heaven" and even the focus pursued by princelings' children; Cheng Jianjun also got several jobs by relying on his higher-ranking father. "It's mixed with wind and water."
Han Chunming, the "Hutong Chuanzi" played by Zhu, was fired from the factory and became a "scavenger" because he was in charge of stealing speculation alone. While being looked down upon, the foreign aunt and cousin Meng came to "join in the fun" and made a fool of themselves as soon as they entered Beijing. They were ridiculed as "Old Tan Er went to town, dressed in velvet and tied with hemp rope around his waist, and bought a bottle of soda and refused to return it".
Although people's environments are different, Han Chunming has not lost his masculinity in Beijing. Although he is poor, he still likes to take care of his relatives in the countryside. In the end, with his shrewd mind and hard work, he mastered "junk" antiques and electrical appliances and became famous in one fell swoop. He not only opened a private museum, but also defeated his opponent Cheng Jianjun because of his kindness and loyalty, and finally won the love of Su Meng.
