What do the Nanjing Border Armed Police do? How is the treatment?

There are many types of armed police. I think the border armed police are mainly responsible for border inspections, border security and border patrols in some areas, combating smuggling and anti-smuggling at sea. Treatment should be graded! The official ones cost more than 3,000 yuan! Ordinary soldiers only cost 1,000 yuan to 2,000 yuan! Brother, I want to go first and wish you a promotion!
