Senior Scholar Wei Juxian states that the Pangu story is derived from stories during the Western Zhou Dynasty. He cites the story of Zhong (重) and Li (黎) in the "Chuyu" section of the ancient classics Guoyu. In it, King Zhao of Chu asked Guanshefu (觀射父) a question: "What did the ancient classic "Zhou Shu" mean by the sentence that Zhong and Li caused the heaven and earth to disconnect from each other?"
