Extended data:
In the modern living myth, the shadow of the sun candle and the moon can no longer be seen, and people know little about it. The sun candle is only active in some rare ancient books and some scattered records in bronzes. As for the shadow of the moon, there are few records, only a few bronze inscriptions and some descriptions of Oracle Bone Inscriptions, which is a great regret in the mythological world.
The original origin of Tiansiling is still inconclusive. According to the arrangement and research of astronomical data in Oracle Bone Inscriptions unearthed in Yin Ruins, it is found that images of four spirits have been produced in Oracle Bone Inscriptions in the early Yin Shang Dynasty, and the names of 28 houses were recorded for the first time in the lacquer box of the tomb of Zeng Houyi in the Warring States Period unearthed in Suixian County.
