What is the relationship between Guangdong Frontier Corps and Guangzhou Frontier Inspection Station?

These two units used to be superior and subordinate. 1998, due to the work reform of nine border inspection stations in China, they were separated administratively, but their business remained unchanged, except that the border inspection corps also included border inspection business, which was basically similar to foreign immigration offices and was responsible for the entry-exit inspection and supervision of people and vehicles. The former is under the jurisdiction of the Fourth Bureau of the Ministry of Public Security, while the latter is directly under the Sixth Bureau of the Ministry of Public Security. The most important point of the two is that the former is the army active duty system and the latter is the career lifelong system.
