卓球, also known as table tennis, is a fast-paced sport played on a rectangular table divided by a net. Players use small paddles to hit a lightweight ball back and forth. The objective is to score points by making the ball land on the opponent's side of the table without them returning it. The game can be played in singles or doubles format, with each player or team taking turns to serve. 卓球 is popular worldwide and is governed by the International Table Tennis Federation (ITTF), which organizes major competitions, including the Olympics and the World Championships.
