? Tennis was born in the French court in 12 century. At that time, people didn't call it tennis, but called it? Handball game? As the name implies, this sport is to hit the ball with the palm of your hand and touch it. At first, the ball was not what we see now. It is made of cloth and filled with feathers, which can reduce the damage of opponents. At that time, the two sides did not fight each other on both sides of the net, but across a rope.
? By the17th century, there were already rackets. Louis X loved tennis very much. He didn't like playing outdoors, so he built an indoor tennis court in the palace, and the first tennis player and indoor tennis court were born. Because this sport has certain requirements for rackets, venues and balls, it is called aristocratic sport. After it was introduced into China, people's life gradually improved, and tennis developed in China. Before inventing modern tennis, Major winfield studied and borrowed many elements of French royal tennis, including some skills and rules, and applied for a patent, so tennis was handed down.
? As mentioned earlier, the original tennis balls were sewn with strips of cloth and filled with feathers. Later, it was made of leather or animal intestines, filled with lime, dirt, sawdust and even human hair, but it failed to achieve the expected results. It was not until Louis Xi, after a long period of practice and research, that tennis was made with a unified standard, that is, made of fine leather and filled with wool. In order to make the bare rubber ball easy to manipulate and make the movement more interesting, the surface is covered with a layer of fluff. In this way, if the ball accidentally hits a person, it will not cause too much harm to the human body, and it will also increase the friction of the ball in flight, make the ball rotate more strongly, and reduce the speed of tennis, so that players can better master the sport.
