The origin and development of volleyball: Volleyball began in 1895 in Holyoke, Massachusetts, when a YMCA physical education supervisor named William G. Morgan was coaching people. During the practice of various physical exercises, he felt that the basketball game that was popular at the time was good, but it was strenuous and not suitable for older people. Therefore, after a period of exploration, he created a new game: playing on the Internet. The game is played on the court with basketball linings. There is no limit to the number of players on both sides but they must be equal. Each player has one side. Passing the bladder back and forth on both sides of the net to make it fly in the air was the earliest prototype of volleyball. The initial volleyball game was just a pastime. The number of players, the size of the ball, and the score were all decided by temporary negotiations between the two parties. Soon this game became widely spread in the YMCA, and was first named "Mitontte" by Morgan, Springfield City Sports Director Dr. Frank De, and Fire Department Director Lynch. , after the first exhibition game in 1896, it was renamed "Volleyball" and the name has been used to this day. Due to geographical location, the spread of volleyball first spread to Canada, Cuba, Brazil and other countries in the Americas, and then to Asia, Europe and other places. The channel of introduction is mostly through the church. Volleyball was introduced to Asia in 1900, first from India, and then spread to other Asian countries. It was introduced to Asia through the 16-man system, the 12-man system, the 9-man system, and finally developed into the 6-man system. It was introduced into Europe slightly later than Asia. During the First World War (1914-1918), volleyball moved to the European continent as U.S. soldiers traveled across the ocean. At that time, the rules of volleyball began to gradually improve, and player rotation, 15 points and 6 players were adopted. system.
