There is one thing I can't understand in the movie Storm. What do you mean by the video recorded by Hu Jun and Andy Lau?

Hu Jun has been committing crimes, and Andy Lau hates his guts and wants to put him in prison. When the little girl and witnesses died, they thought that Hu Jun (Cao Nan) had caught up with him to vent, but because there was no evidence, they had to vent, so they couldn't catch him. So Andy Lau knocked him out, smeared the little girl's blood and some hair on Hu Jun, created this "evidence", and finally arrested Hu Jun. . It happened that the scene of forging evidence was filmed. If it is exposed, he is not a policeman and Hu Jun is innocent, so everyone who knows this video will be killed. . . . Later, Lin Jiadong (Tao) told Dehua that the little girl and the witness were actually killed by Lv Liangwei (Page), which means that Andy Lau not only perjured himself, but also wronged Hu Jun, so he turned himself in and was finally jailed.
