"Zhendong, come on!" Kong Zhendong's backhand pull in the translation of his body is so beautiful that the friends who watch the ball are unconsciously cheering for him.

In the 21st century, the rules of serving are becoming more and more rigorous and detailed.

The rules are complex, but the core is clear, that is, to achieve unobstructed, no leverage, and no surprise attacks.

There are only a few rules to understand briefly: first, throw more than 16 centimeters vertically, and second, the ball must be free fall before it can be hit. Thirdly, during the stroke, no part of the body is allowed to be in front of the horizontal line of the ball, causing obscuration.

The rules require that the ball can only be hit vertically and in free fall, that is, to avoid the force in other directions forming a resultant force with the racket when throwing the ball, increasing the power and rotation. As for the description of the blocking, except for the description of the hand blocking, no part of the body can be in front of the horizontal line of the ball, mainly to limit Liu Pang's twisting waist and half-turning serve.

The serving violation that Ding Ling, the great demon king of later generations, was once made crying by the referee, which was actually very wronged. She used the backhand chopping serve taught by Kong Zhendong, but unfortunately the woman's strength is relatively small, in order to facilitate the force, her center of gravity is pressed relatively low, and in the eyes of the referee, it is easy to think that the serving height is not enough 16 cm.

In fact, the 16 cm in the serving rules is difficult to judge with the naked eye, whether the serve is illegal, should judge whether she borrows strength, whether she blocks, whether she attacks, and bites 16 cm to death with her own feelings, it is the referee who deliberately shows his authority and controls the game.

Kong Zhendong is going to teach Hong Tao today what is the serve stipulated by the international regulations.

Kong Zhendong put the ball on the racket with his left hand and weighed it slightly, then threw the ball upright 20 centimeters, rubbed his right hand with his forehand, and directly sent a short ball.

Strike! Hong Tao was happy to see the hunt, and the bet was right!

Hong Tao saw that Kong Zhendong was only 1.6 meters, and bet that he would not dare to retreat from the stage, but only dare to fight with himself for a short ball in front of the net.

Under normal circumstances, the ball in front of the net is naturally dominated by the short Kong Zhendong.

But Hong Tao is a semi-professional athlete, semi-professional amateur, and it is difficult to say victory or defeat when he encounters a fierce fight, but he has delicate skills in front of the net, and he will definitely blow up the ten-year-old little hairy child.

Hong Tao received the serve and swung short, but still hit the ball to Kong Zhendong's backhand.

Kong Zhendong quickly stepped forward, dialed his backhand quickly, and directly hooked the ball diagonally to Hong Tao's backhand.

Is this hairy boy's backhand really so strong? Hong Tao was depressed, fought backhand, and fell into the wind again.

Hong Tao kept an eye on it, put a straight short ball, and attacked Kong Zhendong's forehand. Then the body starts to return to the right and prepares the forehand position to cut the ball.

Kong Zhendong suddenly exerted his strength, and his forehand exploded forward to rush a board, and the hit was still a straight line, but the long ball went straight to Hong Tao's backhand far platform.

Hong Tao's body had just returned to normal, and the table tennis ball had already hit the table and bounced to the onlookers of the sports school, and Hong Tao was beyond his reach.

Hong Tao had 10,000 grass horses galloping past in his heart, and what about the shortening of the promise? What about the skills in the platform? Can you still have fun playing so suddenly that you've become fast and long?

Seeing Hong Tao's tangled face, Kong Zhendong was inexplicable: buddy, serving short balls is an international practice, so as to avoid the opponent receiving the serve and attacking. The short ball dispatches the opponent to have a chance, of course, the long ball is decided, and I am not accompanying you to play the short house~~

Ye Xiaoya has already turned into a fan girl, she shook Guo Bing and said, "Zhendong's style is wrong!" He is a horizontal board defender, facing Hong Tao, who is attacking continuously on the straight board, and he doesn't win more than four boards every time? Who exactly is an attacking player? ”

Guo Bing joked: "This shows that Zhendong is not suitable for table tennis, he is defending and counterattacking." He's made for the Premier League and tomorrow I'll take him to football! ”

"You dare, tomorrow I will accompany Zhendong to practice, he plays well, I will find Uncle Yu, and enter the capital team in the future." Don't lead him astray, you scourge. Ye Xiaoya angrily rewarded Guo Bing with a chestnut!

After scoring the first point, Kong Zhendong continued to serve.

Kong Zhendong threw the ball high this time, and the height of the table tennis ball flew directly overhead.

This is a very handsome high toss serve.

Some sluggish Hong Tao was in good spirits, and the little hairy boy just loves to be handsome. As soon as you are handsome, it is your death.

In the early 90s, the Swedish Waldner and Persson were the models of the high-tossed hair balls.

This kind of serve is quite atmospheric and gentlemanly. It also reflects the absolute self-confidence of the Swedish king.

They firmly believe that in the face of their absolute strength, they do not need to serve and play tricks to gain an advantage, and their all-round skills are enough to crush any opponent.

The high toss overhead serve is also very marketable in the folk, which has nothing to do with the gentleman's atmosphere, the main reason is - handsome!

Although the high throw serve is handsome, but its fatal flaw is that the table tennis falls for too long, giving the opponent time to fully prepare, so after the masters of various countries have studied thoroughly, in the new century, even the Swedes do not dare to send a high throw over the top, and this most open and unobstructed way of serving has also sunk into the long river of history.

Hong Tao is ambitious and ready to use sufficient preparation time to improve the quality of his serve and reflect his advantages in the first three boards.

But before he was ready, the ping ball spun incredibly fast. It's a long ball!

Hong Tao can only choose to retreat, and all the preparations for receiving the serve can only be invalidated, and he will barely push back first.

Syllable! Yes! Hong Tao and the onlookers screamed in surprise.

Hong Tao's normal force actually knocked the table tennis ball far away.

Kong Zhendong served and scored directly, 2:0.

Kong Zhendong's high-toss overhead serve is an improved version of his later coaching, because each active athlete has their own advanced serving method, so there is certainly no need to teach this outdated serving method.

Although the high toss serve has the weakness of taking a long time and allowing the opponent to be fully prepared, the higher the toss, the lower the fall, and the faster and faster the ball speed due to gravitational acceleration is an excellent means of use.

Kong Zhendong's new serve not only makes the most of the ball's falling speed, but also prepares three hitting points from high to low.

This is the most invincible part of the new high-toss serve, through different shot positions, so that the opponent cannot judge the timing of the serve, which is probably unthinkable by the ITTF.

Originally, the purpose of improving the serve was to reduce the surprise effect of Liu Pang's concealed serve, but Kong Zhendong has researched a new raid effect with different hitting heights and timings, and it is completely in line with the international service rules!

Hong Tao was completely stunned, he only felt that his eyes were not good, and he didn't pay attention to Kong Zhendong's service timing.

It wasn't until Hong Tao ate two more high-toss serves, and the score became 4:0, that he realized! Nima himself was engrossed in staring at the serve, only to find out that the timing of the three serves, the hitting height was completely different, and he couldn't defend himself!

"Come on, Zhendong! The last ball! Ye Xiaoya applauded and cheered, Zhendong was about to win his father's racket back!

Hong Tao's face turned red, but he really didn't dare to retort loudly at this time that he could chase five balls in a row.

At the very least, you must win the goal to save face!

Kong Zhendong threw high again and was about to serve, and when he heard Ye Xiaoya's encouragement, he remembered that this was the last ball, and he had to think about it, how to teach Hong Tao a lesson in the end?

Kong Zhendong actually staged the most classic of football star Ba Shen at the moment of high throwing serve - thinking about life!
