Sailors are in contact with the sea just like sailors, that is, sailors have to work on aircraft carriers, various ships or submarines in China, so they can be called sailors.
There are many opportunities for sailors, such as exams and transfer to non-commissioned officers. Being a navy is good, but being a sailor is even more remarkable. There is a saying in the army that all armed forces can fly, the armed police force is that, and the leadership is to put out the fire. Everyone in the army knows what it is.
