Hello, the director of the office and the section chief of the safety supervision bureau are originally at the same level. Because of the different division of labor, the office director belongs to the "general manager" in the bureau, and the office director belongs to the department leader in charge of business in the bureau. Therefore, internally, the director of the office belongs to the lead department leader and can arrange work for the section chief. However, when the safety supervision bureau carries out business work abroad, the section chief has greater authority.
