What is "zhuanxu"

Zhuanxu ( Chinese: trad. , simp. , pinyin Zhuānxū), also known as Gaoyang ( t , s , p Gāoyáng), was a mythological emperor of ancient China.

In the traditional account recorded by Sima Qian, Zhuanxu was a grandson of the Yellow Emperor who led the Shi clan in an eastward migration to present-day Shandong, where intermarriages with the Dongyi clan enlarged and augmented their tribal influences. At age twenty, he became their sovereign, going on to rule for seventy-eight years until his death.
