No, it is difficult for ordinary soldiers to be promoted during their service! It is the heads above the major military regions who have the final say! For a major military region, there are only one or two people to be promoted! Unless you have made a special contribution to the army, especially outstanding, there must be connections above the commander, so that you have a better chance of promotion! Or have a merit citation class ii above, direct promotion! But now it is a peaceful time, and it is very good for ordinary soldiers to make a personal third-class merit during their service! Not everyone has the opportunity to take the military school entrance examination. Since you have connections, I can help you get a place to take the entrance examination for the military academy. The rest is up to you!
