Who is the second-class police officer?

There are two kinds of second-class police officers. One is the name of the police rank, the lowest rank of the police rank, and there is a four-pointed star flower on the epaulettes, which is awarded to the people's police who have entered the police with high school education. At present, there are many border police stations in the Immigration Bureau, because the armed police have been transferred to the Immigration Bureau, and many non-commissioned officers with low academic qualifications have awarded this police rank; There is another level after the reform. Generally, police officers who have just joined the work are designated as second-class police ranks.
