Weiqi is a mind sport that originated from China. It has been popular since 2,500 years ago. Weiqi has been spread to the Korean Peninsula and Japan in Han Dynasty and Tang Dynasty respectively, and gradually spread to all over the world. It fully embodies the oriental way of thinking and ideological system, and is one of the major contributions China has made to the world civilisation. Weiqi made its Asian Games debut in 16th Asian Games, Guangzhou, in 2010.
The black and white stones are displayed on a Weiqi board with 361 crosses made of 19 vertical lines and 19 horizontal lines. It is played as the follow rules:
1. Weiqi is played by taking turns to put black and white stones on the cross of the board. One can only go one stone each time.
2. The cross made by the vertical and horizontal stone line is the "Qi" of the stone. When the "Qi" of one stone or connected stones is completely occupied by the other player, it is called "dead stone" and has to be lift up from the board.
3. Finally, who wins more area on the board wins the game.
4. The act of lifting a stone for each other is called "Jie" (rob). In order to avoid non-stop game with repeated lifting, one must not lift immediately in return after being lifted.
