Customs: (customs) It sounds scary, but it is actually a tax department. He basically ignores the crimes of smuggling. It only supervises and inspects all goods and articles entering or leaving the country and collects customs duties according to regulations. There is an anti-smuggling bureau. The implementation of vertical management system is divided into three levels in organizational structure: the first level is the General Administration of Customs; The second level is Guangdong Branch, two special commissioners' offices in Tianjin and Shanghai, 4/kloc-0 directly affiliated customs and 2 customs schools (Shanghai Customs College and Qinhuangdao Customs School); The third level is the 562 subordinate customs agencies under the direct jurisdiction of the customs. Therefore, reporting to the grassroots customs is the same everywhere.

Maritime affairs: MSA for short, it's full of cows. Students, this is the management of the sea. . . . It can also be called maritime traffic police. I weighed it. . ) The Maritime Bureau was formed by the merger of the former People's Republic of China * * and the State Bureau of Port Supervision (Traffic Safety Supervision) and the former People's Republic of China * * and the State Bureau of Ship Inspection (Ship Inspection Bureau of the Ministry of Communications). The Maritime Safety Administration is an institution directly under the Ministry of Communications and implements a vertical management system. However, it should be noted that at present, the maritime administrative system is divided into two categories: maritime bureau directly under the central government and local maritime bureau, so "Shanghai Maritime Bureau" and "Shanghai Maritime Bureau" are not an organ, the former belongs to the Maritime Bureau directly under the Ministry of Communications, while the latter is the administrative organ of Shanghai, with different levels, establishment and law enforcement scope.

They are all first-line grassroots posts, and they are all hard. You'd better choose a place.
