There are many theories about the origin of table tennis, and the most popular one is that table tennis originated in England at the end of 19th century and was derived from tennis. It is said that one day at the end of the 19th century, London encountered a rare sultry weather. After watching the Wimbledon tennis match, two young British aristocrats went to a single room in a fine restaurant for dinner. First, use the wooden box cover of cigars as a fan, and then discuss tennis skills and tactics. Pick up the cork bottle of champagne as a ball, use the big dining table as a table, pull a string in the middle as a net, and use the cigarette box cover as a racket to play. The waiter cheered on the side, and the female shopkeeper who heard the news could not help but blurt out "Table Tennis", which named table tennis "Table Tennis". At first, table tennis was just a court game, and its name was not table tennis, but "Flim—Flam", also known as "Goossime". Later, an American named Heath invented a hollow toy ball called "celluloid". In about 189, the Englishman James? 6? When James Gibb traveled to America, he saw a toy ball made of celluloid and brought it back to England to replace the original solid ball. At that time, the racket had a long handle with parchment on both sides and a hollow middle. When playing celluloid with this racket, it made a "ping" sound, and when it landed, it made a "ping" sound. Thus, the name of ping-pong was born. This kind of toy ball is called ping pong. It started in Europe and America, and then spread in Asia. A British sporting goods company first used the word "Ping-Pong" as an advertising name and registered it as a trademark. In 1891, Charles, an Englishman? 6? Baxter applied for a license for table tennis as a commercial patent. The International Table Tennis Federation (ITTF) is a consortium of table tennis organizations participating in the ITTF. The current membership of the International Table Tennis Federation has exceeded 2, making table tennis one of the three sports with the largest number of participants in the world. Its abbreviation is: International Table Tennis Federation, and its abbreviation is: ITTF. It was founded in London, England in December 1926. Its headquarters was originally in Hastings, East Sussex, England, and moved to Lausanne, Switzerland in 2. December 12, 1926 in Ivo, London, England? 6? In the library of montague's mother, Ms. Swaythling, the first historic Congress of the International Table Tennis Federation was held. At the meeting, the ITTF constitution and competition rules were formally adopted. As the word "Ping-Pong" was found to be a commercial registered name, the ITTF was renamed as "Table Tennis" Association, which has been in use ever since. Before the 192s, table tennis remained in the game stage. Invitational tournaments have been held since the 192s. From December 6 to 11, 1926, the 1st World Table Tennis Championships was held in McMoO Hall, Frington Street, London. The competition consists of five events: men's team, men's singles, women's singles, men's doubles and mixed doubles. In addition, there are men's singles consolation matches. Because the total number of female athletes participating in the competition is only 16, there is no women's team and women's doubles competition.
