What is Qizi chess among the new Weiqi teenagers?

Qizi chess is a variant of Weiqi, also called Guiguzi chess. It is played on a standard Go board, but the pieces used are different, with only seven pieces on each side. The goal of the game is to eventually occupy more territory or annex each other's stones in a closed and interconnected space. In addition, some rules of chess Hebi are also different from those of standard Go, such as no lifting.
