That day, Ding Wu traveled to Shanghai with his good friend Li Guo. Li Guo, who always regarded women as dung, kept boasting about how he could easily lure women and then dump them ruthlessly. Suddenly, Ding Wu said that Na Pang would not be like that. Li Guo replied that all women were the same in this regard. Ding Wu insisted that Na Pang would never do such a thing. In order to verify his correctness, Ding Wu turned back to Beijing before even leaving the Shanghai airport. He wanted to slap his friend in the face with the truth - there were pure women, and her name was Na Pang. But then, the most terrible thing happened. Back at home, Ding Wu found a man named Xia Li with Na Pang.
