网球运动的品质之一就是独立。1924年,由于很难在职业运动员与业余运动之间划出一条分界线,国际网联同国际奥委会发生冲突,导致网球退出了奥运会,直到1988年汉城奥运会,也就是公开赛时代开始20年之后,网球才成为正式比赛项目。 One of the qualities of tennis is independence. In 1924, as it was difficult to draw a line between professional athletes and amateur sports, the ITU clashed with the IOC, causing the tennis to withdraw from the Olympics until the Seoul Olympics in 1988, the era of the Open. Years later, tennis became an official event.
