In 2002, Ye Tianyou, Qin Feng, and Hu Xiaoyue were chasing a criminal. After cuffing him, they heard Hu Xiaoyue calling for help. They rushed over and found that Hu Xiaoyue's clothes were caught on the iron railing and he was hanging in the air. Ye Tianyou and Qin Feng rushed to rescue him.

At this time, Deputy Director Chu Qingtong of the Provincial Department proposed to transfer Qin Feng to the Port and Shipping Branch for training. Qin Feng declined Chu Qingtong's transfer because he still had cases in hand. Both Qin Feng and Ye Tianyou felt that someone wanted to block Qin Feng's investigation.
