The transparent coffin of the Yellow River was discovered in the 1980s when the silt in the middle and lower reaches of the Yellow River was cleaned. The dredging project lasted a long time and was very difficult, because everyone accidentally dug a transparent coffin from the Yellow River during dredging.

According to the research of Mr. Feng Shui, according to some experienced local old people, this mysterious transparent coffin of the Yellow River should have been buried here long ago to suppress floods. There has been a terrible saying in the local area that the Yellow River flood was actually caused by evil spirits.
As for who lies in the transparent coffin, it is likely to be a master with extraordinary spiritual strength, or a defender who voluntarily sacrificed himself to save everyone, or a local old man who died with great prestige.
