Hello, the supervisor needs to participate in certain continuing education and training every year to keep the professional knowledge and skills updated and upgraded. According to "People's Republic of China (PRC) Supervision Regulations", supervisors should attend at least 40 hours of continuing education and training every year. At the same time, supervisors also need to participate in the examination or evaluation of the relevant national or local supervision business regulations to ensure their ability and level to continue to engage in supervision work.
