The pursuer killed Song because the boss died. He was afraid that Song Hui would tell the police. While chasing Song and his son, Song and his son had an accident and rolled down the hillside. Dong Xiaofeng just ran for his life, without considering whether they were alive or dead.

The play tells the story of a murder in a western village. Song, Wang Youquan, were listed as suspects by the police, and the three opened the story of black escape.

Dong Xiaofeng came after Song and his son because he didn't kill the boss, but after the boss died, he was worried that Song and his son would tip off the police, so he came after them. Unexpectedly, Song and his son rolled down the steep slope halfway.

I felt that Song and his son couldn't live if they rolled down from such a high place, and their legs and feet were inconvenient, so they didn't go down to see if people were dead or alive. For him, the Song father and son are meaningless whether they live or die. He just wants to run away with his girlfriend.
