In the TV series "The Knockout", Meng Dehai's daughter, Yu Meng, pretended to be a net friend from Li Hongwei to meet in a bar in order to get evidence of Li Hongwei's drug abuse. In order to gain Li Hongwei's trust, Yu Meng also ate the imitation drug pills given to him by Yang Jian in front of him.
When Li Hongwei's younger brother found out that Yu Meng and Anxin knew each other, he understood that Yu Meng approached him on purpose, so he kidnapped Yu Meng.
At this time, in order to compete with Li Hongwei's father Li Youtian, Gao Qiqiang sent his younger brother Gao Qi Sheng and his men to kill Li Hongwei, which happened to save Yu Meng.
