Beijing's Jiudaowan Hutong is full of twists and turns. Yang Shumao, Ye Fei, Shi Xiaona, and Zhao Yajing, who grew up together in the hutong, have also experienced the complex and bumpy nine bends of life. The story begins in the winter of 1979 when Yang Shumao returned to the city after joining the production team... Shi Xiaona was Yang Shumao's first love, but the good times didn't last long. Her father deliberately sent his daughter to Hong Kong to study at university... Ye Fei was born in an intellectual family, Shu Yawenjing had a good character, and was a key figure influencing Yang Shumao's worldview. Yang Shumao was called "Silly Mao" by his father at home. In a typical old Beijing family, his mother seemed to be the most "reasonable" and managed her children obediently. In order to catch up with Shi Xiaona (@陈瑶Sebrina), Yang Shumao (@韩东君ElvisHan) and his buddies gave up their iron rice bowls and went to Guangzhou to find Zhao Yajing (@种丹妮), their "classmate" in elementary school. Unexpectedly, Yang Shumao, who has low emotional intelligence but high IQ, is a "material" for doing business. He established himself in Guangzhou in one year. Zhao Yajing has a crush on him, but Shi Xiaona is in the way. God-given opportunity, Shi's father "sanctioned" Yang Shumao for the second time, which made Yang Shumao thoroughly realize the difference in social classes and gradually drifted away from Shi Xiaona. What Zhao Yajing didn't expect was that she had been secretly trying to win over Yang's mother (@萨日娜srn), who had already determined that she was her future daughter-in-law. But at this time, Yang Shumao and Ye Fei (@热依扎) almost simultaneously discovered that they were in tune with each other and were the most intimate life partners. Once this emotion came out, they swore to each other and prepared to get married. But things were not so easy. They had to face Yang's mother, who was "extremely skilled". Even if Yang Shumao had great skills, he could not escape the palm of his mother. Yang Shumao and Ye Fei had been through ups and downs for more than 20 years. Their fate took nine turns. The love between the two withstood the test of time and finally lived a happy life.
