One is that conscripts become non-commissioned officers after the expiration of their service, the other is that conscripts are admitted to non-commissioned officers' schools, and the other two ways are that college entrance examinations directly recruit non-commissioned officers, and college graduates directly recruit non-commissioned officers to join the army.
