Which big brother who knows kung fu teaches my brother how to turn a gun when practicing traditional gun skills?

First, hold the gun in both hands and put it on the right side of your body, with your right hand down, your left hand up, your right hand backward and forward, and your left hand backward. Then shoot with your right hand, turn to the left side of your body, turn to the right side of your body, turn to the right side, and take it to the left repeatedly. Simply put, turn right twice and turn left once.
