Playing on grass, after the ball lands, there is a noticeable slippage, which greatly reduces the time for players to prepare to hit the ball.

The grass cover is uneven at first, and as the game progresses, the roots and crust of the ryegrass are exposed, and friction increases here.

In addition, the foundation is also uneven, so the rebound of the ball on the grass is very irregular, which requires players to be familiar with the performance of the grass on the one hand, have good anticipation and agility to adapt to the situation, and on the other hand, try to use the ball as much as possible to cut the ball and volley.

Chopping on grass is a bigger threat than on other courts, but volleying on grass is not an easy task. Because the speed of the ball is fast back and forth, there is not enough time to surf the net, and even if you go to the net, you are faced with a much faster return than other courts, and the adjustment of body techniques is also very hasty, and the certainty of volleying is not very high (compared to the carpet). In the last plane, even players of the caliber of Raft and Sampras often made incredible mistakes. However, the grass must be more netted, and if it stays at the bottom line, it will be more difficult to deal with the rebound ball that lands.

The most advantageous aspect of grass is that it amplifies the power of the serve.

On the grass court, the same 180 kilometers of serve, on the one hand, it is much more difficult to receive the serve, the friction speed loss of the ball through the grass is very small, and the bounce height is also low, leaving little room for the receiver to react.

On the grass court, a player like Zhang Yiyang, who serves heavily with a heavy gun, has a chance to show his strength. Of course, it is not impossible for a bottom-line player like Du Xinghe to play, but only those who are in moderate shape and have a sensitive response. Players who anticipate passing the serve can use the power of the incoming ball, leverage the power of the play, and at the same time supplement the fast running to create a chance to cross the ball, in order to reach the peak.

Du Xinghe is now more and more interested in tennis, and it is the magical court of Wimbledon that he wants to experience the most. He had never played on the grass before, and listening to what Zhang Yifan told him, he was quite fond of Wimbledon.

Du Xinghe has read the gossip magazine and knows that Zhang He Yaping, the mother of the "mother of the country" Zhang Jiajia. Almost every year at Wimbledon, I go to watch it live. It is said that Zhang He Yaping is very affectionate about Wimbledon. She used other names to compete at Wimbledon that year. She also reached the top 32 of the women's singles, which was the best Wimbledon result for Asian tennis players regardless of gender.

With the popularity of tennis in Asia in recent years, the level of Asian players has gradually improved, and it is only after breaking through the shackles of the top 32 that they have broken through. At Wimbledon though. The best result of Asian players, represented by China, is only the top 8. Regardless of gender, they have yet to reach the semi-finals.

At present, the best result of Chinese players in the Grand Slam is the semi-finals of the Chinese Grand Slam, overall. The level of tennis of Chinese players is not yet the mainstream leader in the world tennis world, just as the Chinese Grand Slam itself has been criticized by some people.

Once upon a time, some tennis powers, led by the United States, did not recognize the achievements of Chinese in tennis.

However, in recent years, as China's Grand Slam has become more and more successful, players from some of the world's mainstream tennis powers have begun to pay more and more attention to this event, after all, the points of this event are the same as the other four Grand Slams, and they can get the highest points in tennis competitions.

For those who challenge for the top 10 or better, the China Open, the final Grand Slam of the year, held at the end of October, is the tournament they have to compete for.

However, for other official series held in China, those tennis players do not pay much attention, except for the Shenhai Championships, the pre-warm-up tournament of the China Open after the end of the US Open every year, there are many strong players to participate in and adapt to the Chinese competition environment, and other tennis tournaments held in Zhongguo rarely have top players gathered. After all, for Western golfers, the journey back and forth between East and West can be a hard job.

For example, in the 250-point men's championship held in Fuwan, there were almost no top 10 players in the world to participate. This competition is usually a chance for local Chinese male players to grab points.

In this Fuwan Championship, one-third of the 64 players participating in the tournament are Chinese local players, and the top seed of the tournament is also the current leader of Chinese men's tennis, Zhang Di.

He has already lifted the trophy in Fuwan for the second time in a row, and this time he is bound to defend his title, and if he wants to maintain his top 20 position before the French Open, he will have to win the Fuwan Open in order to secure a good spot at the French Open on June 15.

Almost all the people who came to practice at the Blue Moon Bay Tennis Center this morning were professional players who were going to participate in the Fuwan Championship. The Fuwan Championships are the highest level of men's tournament held by the Blue Moon Bay Tennis Center, so the venue will provide convenience for players participating in the Blue Moon Bay Tennis Tournament every year, and the venue will be open for them to practice a month before the start of the tournament.

This time, Du Xinghe and Zhang Yifan were able to come to Blue Moon Bay to adapt to the venue, all thanks to Zhang Yiyang as a wild card player of the Fuwan Championship, and it was Zhang Yiyang's application to the Blue Moon Bay Tennis Center as a participant in the Fuwan Championship.

They were scheduled to practice at 8 o'clock on the 9th driving range, which was a full morning of practice.

The No. 9 driving range is a large driving range at the Blue Moon Bay Tennis Center, and it is a standard-sized contact court with doubles lines, unlike some small driving ranges with a narrow and narrow singles area.

However, unlike the regular venue, the area of the driving range is still much smaller, there are not too many peripheral areas outside the line, and both sides are covered by nets to ensure that the training of the players next to them is not affected.

This kind of professional-intensive tennis center practice courts are lined up one by one, and this morning, not only Zhang Yiyang and they came here to train, but almost all the standard practice venues were reserved by professional players.

Du Xinghe and the others arrived early, and after parking the car and registering, they stepped on the No. 9 practice range at eight o'clock. At this time, there were no people in the next few practice ranges.

Although it is a practice field, the ground is paved with the same thickness and material of plastic as the official competition venue, and the fine rubber particles are the biggest feature of the Blue Moon Bay Tennis Center, which can provide great friction when the ball bounces to the ground, and its friction coefficient is even higher than the Chang'an Central Tennis Court, also known as Chang'an Yaping Court, the final venue of the Chinese Grand Slam, and is one of the most grinding courts in China.

It was the first time for Du Xinghe to set foot on this kind of high-quality rubber hard field, and before he started practicing, as soon as he rubbed his feet, he obviously felt that there was a big difference from the cement field of Fuda. This court not only has high friction against the ball, but also has a higher friction on the sole, and when moving on such a field, there will even be a feeling of "sticky" feet, which is very awkward.

"Mr. Du, how do you feel, it's different here from Fuda." Seeing that Du Xinghe was rubbing the ground with the soles of his shoes to find a feeling, Zhang Yifan asked Du Xinghe with a smile. She herself has already played a lot of matches in Blue Moon Bay, so she knows a lot about the venue in Blue Moon Bay. She knew why Du Xinghe rubbed the soles of his shoes on the ground.

Du Xinghe tried it a few times and said: "You can't use sliding steps on such a court, you can't slide at all, it's too sticky!" ”

Zhang Yifan pointed out: "In fact, it is not suitable to use sliding in the practice field of Fuzhou University, all hard courts are not suitable for sliding steps, and it hurts the ankle too much." Fuda can slide because the ground is not clean and there is a lot of sand, which is convenient for slipping. But when it comes to regular hard courts, it's hard to skate. ”

Zhang Yiyang also smiled and said: "Yes, Mr. Xiao Du, you must not slip in such a venue, or you will have to break your feet." The official game is going to be played next week, and the injury is a big deal at this point. ”

Du Xinghe wanted to refute the Zhang brothers and sisters, saying that they can actually slide on the hard court, and Xiao De in the previous plane is not a master of sliding on hard courts, but just think about it, what level is he, what level is Xiao De, or don't compare yourself with others, so as not to really hurt yourself.

If you can't slide, don't slide, anyway, sliding is not his killer move, it's just a handsome move, just like he sometimes deliberately flicks his tail when driving.

After the Zhang brothers and sisters took Du Xinghe and Bian Siliang to do some warm-ups, they immediately put themselves into a serious state of practice.

In order to find this kind of plastic hard field feeling for Du Xinghe first, Zhang Yiyang first played a few rounds of singles with Du Xinghe.

It was the first time for Du Xinghe to play on such a hard court, and he tried to experience the bounce of the ball on such a court.

Zhang Yifan has already told Du Xinghe before that this kind of venue is more suitable for Du Xinghe's topspin ball, because the friction is greater, and the bounce of the ball will be higher.

After Du Xinghe got his hands on it, he experienced this remarkable change from the first serve.

He uses the strong topspin serve method that usually serves on the Fuda Stadium to serve on this court, which is an inside corner spin ball, and as a result, after the ball lands, there are obviously more lines to turn inward, and the height of the ball jumping up after bouncing on the ground is 30 cm higher than that of Fuda! Usually, after the ball hits the ground, it will bounce to the left and right positions of Zhang Yiyang's chest, so that Zhang Yiyang can hit the ball.

Serving on the plastic court, he used the most accustomed force to serve, and the ball bounced to the same height as Zhang Yiyang's head! Zhang Yiyang is extremely awkward to catch this kind of ball, and he must take two more steps backwards to catch it in a comfortable position, otherwise he will have to jump up and catch it.

However, in contrast to the large increase in the elasticity coefficient, the ball speed has slowed down a lot, some balls are on the hard court, Du Xinghe pulled out a violent topspin ball, and Zhang Yiyang reacted when it was too late to save. But on the plastic field, there are some balls that Zhang Yiyang has enough reaction time to save.

Overall, playing on such a court, his own topspin advantage has indeed been strengthened, but the overall lethality has not improved much. (To be continued......)
