Passing the ball is a technical action that is completed by kicking the ground and extending the arms with the help of the chest and above, and the amount of the fingers of the wrist. The main function of passing the ball is to pass the ball to the rest of the players to attack or attack directly. Whether a team's offensive ability can be fully utilized depends to a large extent on the team's passing and guessing the edge.

In order to gain superiority and make offensive tactics fast and changeable, the transmission plays a core role. The cushion ball is a technical action to hit the ball with the help of kicking the ground and raising the arm, and the front of the double forearms. The cushion ball is more important in the game than receiving the serve, smashing the ball and receiving the return ball, and it is an important technique to strive for more points and lose fewer points in the game.

The way in which the ball is quickly wiped from the top to make it quickly and unexpectedly enter the court is a remedial style of play to compensate for the over-passing of the ball, which will cause a mistake in the probe, but sometimes this style of play is deliberately adopted to form a two-ball shot.
