The story of Xiaoping in "The City of Desire" mainly tells that Xiaoping, who went to work in the city from the countryside, came to the writer Wu Dongfeng's house to be a nanny, but ruined his life. Wu Dongfeng and his wife Zhang Li have long lost their feelings. The reason why they didn't divorce was for the sake of their son, but Xiaoping's appearance changed everything.

Xiaoping is young and beautiful, and her nature is simple. She doesn't know the danger of human heart. She has been working as a nanny conscientiously, but Wu Dongfeng is gradually attracted to her. When his wife Zhang Li was on a business trip, she had sex with Xiaoping. The two men have been sneaking around without telling Zhang Li. Zhang Li traveled a lot, and their affair was never discovered.

The good times didn't last long. Xiaoping is pregnant. Wu Dongfeng naturally does not allow her to give birth to the child, so she always persuades her to abort the child. Originally, Xiaoping had been hesitant, but her cousin encouraged her to become the mistress of the Wu family through her children. Xiaoping is a rural girl. She also wants to have a birthright and a good life, so she never aborts her children.

There is no airtight wall in the world. Zhang Li still knows everything. After a big fight with Wu Dongfeng, she left with her son. Wu Dongfeng took all his anger out on Xiaoping and told her that she could never marry her. And forced her to the hospital, trying to force her to have an abortion.

Xiaoping has long fallen in love with Wu Dongfeng, thinking that she has found true love, but Wu Dongfeng only craves her youth and beauty. Xiaoping finally understood the truth. She broke free from Wu Dongfeng and ran out of the hospital. They had a quarrel on the road. In the process of shoving, Xiaoping accidentally pushed Wu Dongfeng onto the road, causing Wu Dongfeng to be killed by a car.

Although Xiaoping indirectly killed Wu Dongfeng, she was the biggest victim in the whole story. If it weren't for Wu Dongfeng, she could have found a good man to marry and live a happy life, but Wu Dongfeng ruined her. Wu Dongfeng is an out-and-out love rat, hurting Xiaoping and Zhang Li at the same time. He deserved this ending.
