You must learn basic skills. You should learn how to draw and chop the ball first. Pulling the ball is a topspin, and chopping it depends on your board. If you chop at the lower left, it's a side spin and it's easy to get off the net. In this case, your serve is not a problem, so is mine. It's German. If you shake your hand, it will turn more. If you hit the bottom right, you are right-handed; if you hit the bottom middle, you are backspin. Wiping the side of the ball can prevent you from catching the ball and spinning up and down, but at the same time, the ball you brush past only rotates sideways instead of downward, so that the past ball is easy to be attacked by your opponent. When you rub the ball to make your opponent uncomfortable, you'd better combine backspin and side cut to create opportunities for your offensive score. Any skill is to win the game, so there is no crooked ways. It's not good for your wrist to rub like this, so the ball you rub out doesn't turn very well. In addition, you can't always rub the ball forward with the front end of the racket. You'd better correct this habit.

First, try to rub the ball up and down at the highest point after it bounces. First of all, don't use force on your wrist. First, clean the ball on the stage. When you have a hit rate, use your wrist strength and the rising point and falling point to rub the ball.

When you put a golf ball, you should use a chop to make it out of bounds. Second, learn to hit the ball sideways and backhand, then move your feet to the backhand position and chop the ball quickly. Third, learn to hit the ball forehand in the opposite direction, and make a comeback when moving, which he can't receive. Fourth, chop the ball. You detain him once, and he's finished. By the way, these are basic skills, and I won't talk about many others. You may know something by watching the video, so that you will become a top player (I am only 1 1 year old). Forehand error may be that you are too strong.
