"I had something urgent to do that day, so I'd like to park my car in the garage, and I'll mention it on the second day, who knows my car is being used by them." "A friend called me that night," said Shen. "I said I saw my car in Jinhua and asked if I was on a business trip. I thought my friend was wrong, then I saw that the number of kilometers changed, and I knew someone had opened my car privately." The car that he sent to repair was regarded as the "private car" of the staff of the repair shop. Shen Yue was very annoyed and looked for the boss theory of the repair shop, but because of no evidence, the boss was very good and ended up.
