Within the different prehistoric cultures 4000-8000 years ago in the Neolithic Age of China, a "burst" of Eight-Pointed Star (called bajiaoxing in Chinese) patterns has been found in recent decades. In both northern and southern China at more than 20 prehistoric sites (the northernmost from Inner Mongolia, southernmost found in Hunan Province; easternmost from the Shandong Peninsula, and westernmost from Qinghai Province) these eight-pointed-star patterns have been unearthed. The earliest known of such star shapes was found in the 7800 year old Gaomiao ruins, Hunan Province. Since in the Neolithic Age people lived in remote places, had hardly any means of mutual communication (there is no trace of a written language; information communicated by spoken language spreads slowly), while usage of the eight-pointed-star pattern quickly became widespread, we conclude that the appearance was not a chance event. It is suggested that the possibility that these star patterns were a reflection or depiction of an astronomical phenomenon which was observed by and greatly impressed people who lived in different parts of Neolithic China. Through a comparison with Sun-like patterns discovered in relics of the same period an explanation is preferred by us that the eight-pointed-star patterns recorded and depict a supernova explosion rather than the Sun. Checking supernova remnants in the Galaxy from modern observations, and taking account of the remnant parameters of distance, age and position, It is suggested that the exploded supernovae of Vela and the Cygnus Loop could be candidates for the Neolithic eight-pointed star, the former with a higher probability. It is interesting that even today the remnant of the Vela supernova still has several "horns".
