Is the bone bed a real history?

No. Gu Lin Bed was originally a legendary script, and the traditional drama Gu Lin Bed was adapted according to this legend. Gu Lin Bed, performed by Pu Theater in Linfen, Shanxi Province, was adapted by Zhao Yi, Du Bo and Li Anhua according to the traditional repertoire of Pu Opera which is not real history. History is everything in the past and disappears with the passage of time. History is a real objective existence.
