The origin, place and time of golf are 18 holes. Some people say that it appeared in the Middle Ages, while others say that it may have evolved from the Dutch colvin Movement in the13rd century. Others think that14th century is a household name sport in Britain. The real development of golf began in Scotland. Before 1764, the standard of the course was not uniform, ranging from six holes to more than twenty holes. At 1858, everyone accepted a standard golf course with 18 holes. I didn't start using the package until 1870. At the beginning, the golf ball shell was handmade with horse skin or cowhide, and it was filled with about 2 liters of mature feathers. By about 1880, the progress of material engineering began to produce rubber core balls. 1902 All England Open, the performance of rubber core ball was affirmed, and it began to completely replace badminton core ball. At first, the surface of the rubber core ball was smooth, but the players found that the sunken old ball flew farther than the new one. Now there are more than 300 pits on the surface of golf balls. Rules of golf announced by Royal Old Golf Club of St Andrews and American Golf Association is the golden rule of golf. The charm of golf lies in the players' solemn, calm and elegant sportsmanship. They don't scream in surprise. When you hit a good ball or drive a long ball into the hole, you may just wave your hand, hold your fist, or you may jump lightly (jumping is not allowed on the green). If you don't hit the ball, you will only smile or shake your head. People will see players playing calmly and thoughtfully. They should overcome themselves, control their emotions, not complain, and respect other players. The psychological quality of players is very important. You should be able to know yourself, solve your troubles and motivate yourself. And learn to control emotions, which are invisible killers on the court. Even a little emotion can greatly affect performance. Being troubled by emotions will slightly affect the performance, and seriously will cast a shadow on the players and lose confidence. Not only can they not play their own level in this game, but they will be troubled by the same situation in the future. The improvement of technology will not happen overnight. It is a sport that requires no pains, no gains, and persistent long-term investment. A standard golf course has 18 holes, with a total length of about 6000-7000 yards and a total area of about 60 hectares, which are called 1 hole to 18 hole in turn. The length of each hole is about 100-600 yards. Each hole has a tee, fairway, green and hole. Starting from the tee, there are generally three or more tees with different distances, and the tee farthest from the hole is used by the strongest player; The middle tee is selected by male players; The tee in front is for female players. The middle fairway is the best route to the green. There may be obstacles on the fairway, and there are obstacles such as long grass, Woods and hillsides on both sides of the fairway. Finally, the green, the hole on the green is the end point, and the flagpole is inserted in the hole. Set boundary markers in key areas.
