Wikipedia definition
2. Chinese constellationsChinese constellations are the groupings used by the ancient Chinese to organize the stars. They are very different from the modern IAU-recognized constellations based on Greco-Roman astronomy. Ancient Chinese skywatchers divided their night sky into 31 regions: the Three Enclosures and the Twenty-Eight Mansions. The Three Enclosures occupy the area close to the North Celestial Pole. The stars in the Three Enclosures can be seen all year around.
