The tomb of King Munyong is a major archaeological discovery in South Korea in the 20th century, in which two mirrors with the seven breasted beasts mirror were unearthed. Japanese scholar Takayasu Higuchi thinks that these two bronze mirrors are all Qizi mirrors, while Chinese archaeologist Yang Hong thinks that only one can be called Qizi mirror. According to archaeological findings and literature, Yang Hong's view should be more reasonable. In addition, combined with the archaeological findings in China, it can be found that the Qizi mirror, as an accessory of tomb, may be related to the gender of the tomb owner.
