The police of public security organs belong to civil servants. Now we should recruit from within the public security and newly demobilized soldiers, and of course we should also recruit from the society. When they are selected, they will be tested, including physical fitness test, written test and interview. Not long ago, we set up a special police team in Dalian. Most of the special police officers are recruited from retired military officers and graduates majoring in physical education. Looks like you still have a chance.
But if you want to join the Armed Police Force, that's different. You want to be a soldier, but generally speaking, being a soldier goes through normal procedures and may not be assigned to the armed police force. So what you should consider now is special skills, but not all schools recruit special skills, but as far as I know, many of them are sports majors. So you still have a lot of opportunities.
I hope you can seize the opportunity, wish you good luck and realize your dream!
