BYD's four-level punishment requires a special approval process. BYD has strict control over the second employment of ex-factory employees. It is definitely necessary for managers to enter the factory twice. Go through the special approval process and get Wang Chuanfu's signature. Ordinary employees have relaxed their requirements because they can't recruit people. People who have passed the punishment of level 4 cannot enter the factory. Of course, there are exceptions to everything, that is, Wang Chuanfu can sign and approve.
