[0002] Table tennis ball control practice is an important link to improve technology. In table tennis competition, the landing point of the ball can usually be divided into three levels of high, medium and low, and the characteristics and tactics of each level are as follows: 1. High landing point: the ball is high in flight, usually landing in the high position of the opponent's table. Corresponding tactics: suitable for controlling the space of the opponent, making it difficult to attack, often used for spin ball and high arc ball, and exerting pressure on the opponent. 2. Medium landing point: the ball landing point is at the middle height, usually suitable for flat hitting or pull ball. Corresponding tactics: suitable for rapid counterattack, taking advantage of the opponent's mistakes and rhythm changes, which can be used for various hitting methods. 3. Low landing point: the ball flies low when approaching the table, usually landing in the bottom area of the opponent's table. Corresponding tactics: used to suppress the opponent, limit his hitting options, suitable for attack and powerful attack.

[0003] Understanding the characteristics of these three landing points helps players choose the appropriate hitting strategy in the game and improve the game winning rate. At the same time, in table tennis competition, the table can be divided into front court, middle court and back court, and the characteristics and tactics of each area are as follows:

[0004] 1. Front court. Position: the area close to the net. Characteristics: suitable for quick reaction and short distance hitting, emphasizing technology and control. Tactics: often used for fast attack and interception, suitable for taking advantage of the opponent's mistakes or short ball.

[0005] 2. Middle court. Position: middle of the table. Characteristics: suitable for various hitting methods, giving players more time and space to adjust their hitting. Tactics: suitable for hitting medium and long balls and building offensive, focusing on ball rhythm changes and confrontation. 3. Back court. Position: the area far from the net. Characteristics: suitable for long distance hitting and spin control, players have more time to judge the ball. Tactics: often used for defense and counterattack, creating opportunities through high-quality back ball at the baseline.

[0006] In addition, in table tennis, the table can be divided into left area, middle area and right area, which helps to understand the hitting strategy and tactical application: 1. Left area. Position: the left side area of the table from the player's perspective. Characteristics: suitable for players who use left hand to hit the ball, right-handed players can attack through side spin and angle change. Tactics: often used for pull, side spin serve and suppression of the opponent's return. 2. Middle area. Position: the central area of the table. Characteristics: relatively safe, suitable for various hitting styles. Tactics: can be used for quick response and change of hitting strategy, adjustment of hitting rhythm, and search for attack opportunities. Right area: position: the right side area of the table. Characteristics: suitable for players who use right hand to hit the ball, especially when serving and receiving. Tactics: used for powerful return, hitting the opponent's weak points and creating scoring opportunities through angles.
