Chūzan Seifu

Chūzan Seifu (中山世譜) was an official history of the Ryūkyū Kingdom compiled between 1697 and 1701 by a group of scholar-officials led by Sai Taku. It was a Kanbun translated version of Chūzan Seikan.

Later, it was rewritten into Classical Chinese by Sai Taku's famous son Sai On in 1725, and expanded each year until 1876.
