Qianball is a racket sport similar to tennis or squash. The game can be described as a mix between tennis and squash or as squash without walls. The game can be played by two or four players, or used as practice by a single person. Qianball can be played on any flat hard surface, indoors or outdoors no matter the weather. The game is played on a court a little smaller than a tennis court with both players placed on the same side of the net. The player side of the net measures 7.6 * 7.8 m, and the other side of the net should be app. 10 * 12 m, but there are no exact rules for this.
