An annotation for the statement about JingXing (Great Star) in the most famous Chinese ancient historical book Shi Ji (Historical Records) authored by Sima Qian reads as follows: "There was a red aureole ("Chi-Fang-Qi") which connected with a deep-color aureole ("Qing-Fang-Qi"). Two yellow stars were in the red aureole,one yellow star was in the deep-color aureole". The author of the annotation was Meng Kang, an officer as well as a scholar of the Wei State in the Three Kingdoms period. The same records are to be found in two other Chinese historical books compiled by the authors of later ages in Tang Dynasty --Jin History and Sui History. The scene illustrated by the record of "Chi-Fang-Qi" is very similar to the pictures of SN1987A taken by the Hubble Space Telescope. Let it be noted that although the ancient authors were often with serious wrong understandings of some astronomical phenomena such as supernovae, their depictions about natural phenomena they witnessed were mostly objective, and it was unlikely that they fictionally made the record of "Chi-Fang-Qi". We infer that the ancient observers might have ever watched a very bright supernova with an aureole structure in its remnant and then left such a record. Meng Kang perhaps was the first to give the record about "Chi-Fang-Qi", and he might have lived in the period from about AD 180 to AD250, very near to AD 185, so, here the supernova the ancient people watched was most likely the one in the year of AD 185. This supposition is consistent with the distance parameter of the most possible remnant of SN185 derived by some modern measurements. If the correlation between the record of "Chi-Fang-Qi" and the supernova remnant can be further proven true, it would be an important verification of the modern theory about stellarevolution.
