Liuyu comes from "Li Weng Duiyun", which tells the story of Tao Yuanming during the Eastern Jin Dynasty.

Tao Yuanming, also known as Tao Qian, had the courtesy name Yuanliang, his private nickname was "Jingjie", and his nickname was Mr. Wuliu.

Tao Yuanming's "Biography of Mr. Wuliu" said, "I don't know who Mr. Wuliu is, nor his surname. There is a Wuliu tree beside the house, so I thought it was called Yan."
