Ding Ning's serve, as well as the third board attack of the long ball or half-shot billiard ball with forehand backhand topspin, are her strengths in the first three boards.

Squat and chop to serve, just like chopping firewood with an axe. Below, I will briefly discuss some of the characteristics of Ding Ning's squat chop service based on the five major elements of table tennis technology and combined with Ding Ning's game animations.

1. From the perspective of strength

Squatting and chop serving, generally speaking, the force is more concentrated. The key is to coordinate the whole body to exert force, squat with the whole body, and use the strength of the body. Here, the larger displacement of the center of gravity up and down provides more conversion of potential energy and kinetic energy for the squat and chop serve. It requires higher strength from the players' lower limbs, and the joints, mainly the hip, knee, and ankle joints, are widely opened and closed, which is a major feature of the squat chop serve. Of course, you should get up and recover immediately after the ball is released to prepare for the next shot.

2. From the perspective of speed

According to hand position, Ding Ning's squat chop service is an overhand serve.

After throwing the ball, the ball will fall faster, and the hitting speed must be faster to catch the ball better and deliver a high-quality serve.

3. Viewed from the rotation

particularly emphasizes that Ding Ning shoots with his left hand.

How to judge whether Ding Ning's squat chop serve is left spin or right spin, top spin or back spin, forward spin or counter spin?

1. Determine left and right rotation. Ding Ning uses the front side to chop the ball to left spin; the reverse side to chop the ball to right spin. In terms of spin intensity, most of Ding Ning's serves are mainly strong side spin.

2. Determine up and down spin. If the wrist is used as the fulcrum, the force exerted diagonally upward at the moment of contact with the ball is topspin, and the force exerted diagonally downward at the moment of contact with the ball is backspin.

3. is to judge the forward and reverse rotation. If the wrist is used as the fulcrum, the racket will be hit clockwise for forward spin, and the racket will be hit counterclockwise for counterspin.

Let us make it clear that the squat chop service generally produces side-up or side-down service. It is not pure top-spin or back-spin, but mainly strong side spin.

From the perspective of the opponent receiving the serve, a serve with mainly side spin is treated as side topspin.

4. Viewed from the arc

This aspect is similar to other types of serves. The height of the arc is mainly determined by the center of gravity, and the length of the arc mainly depends on the difference in force between the forearm and wrist.

5. Looking at

Ding Ning's squat chop serve from the landing point, the landing point is changeable. The position is closely related to the bat face. The usual situation is as follows:

stands in the backhand position and serves from the opposite side; it can serve straight lines and "\" slashes.

stands in the middle position and serves the ball from the front; it can serve straight lines and "/" slashes.

The relationship between this stance and the bat face is, to a certain extent, a guarantee of the stability of his serve.

From the perspective of the opponent's reception, it is very important to determine the left and right spin of Ding Ning's serve in advance. In addition, Ding Ning's brief aim when serving also allows the opponent to predict its approximate landing point and type of left and right spin.

For example, many times, Ding Ning stands on his backhand position and uses his forehand and backhand to serve, and many times he serves up Right counter rotation, the concealment and deception is very strong. It looks like a backspin shot that cuts downwards. In fact, Ding Ning can exert force diagonally upwards the moment he touches the ball. It is a very arched side topspin shot. It is easy for the opponent to catch this ball, thinking it is a backspin ball, but it will hit a high ball as soon as it is caught. Ding Ning can immediately catch the ball and grab it to attack.

Ding Ning's squat-cut serve has become one of her trump cards, and it is often her reserved serve to deal with key balls and key points.
