[...]
After Bin's boss is murdered, Qiao suggests that they run away from everything and get married, but Bin isn't interested. One night a group of motorcycles overtakes their car, and the riders begin attacking the driver and Bin. At first Bin fights them off, but there are too many, and they begin to beat him, claiming their intention to "dethrone" him. Qiao grabs Bin's handgun from her handbag and fires a warning shot into the air, and then another, scaring off the attackers. The police tell Qiao that the gun is illegally owned, and asks her whose it is, but she repeatedly claims that it's hers. She spends five years in prison for possessing an illegal firearm, and Bin does not visit her during that time, despite her saving him and taking the fall for him."~Wikipedia
