Background technique

Modern badminton originated in England. In 1873, in the town of Bloomington in Glasgow County, England, there was a Duke named Boufort. When he held a garden party in his territory, several retired military officers who came back from India introduced to everyone a method of using beats to separate the net. Back to the game of shuttlecock, people have a strong interest in it. Because this activity is very interesting, it soon became popular in the social arena of the upper class. In 1893, 14 British badminton clubs formed the Badminton Association, the predecessor of the All England Open. Since 1992, badminton has become an official event of the Olympic Games.
