[1] Bukūri Yongšon was claimed the progenitor of the Aisin Gioro clan by Hong Taiji,[2] which would be the imperial family of China in the future.
According to the legend, three heavenly maidens, namely Enggulen (ᡝᠩᡤᡠᠯᡝᠨ,[3][4] 恩古倫), Jenggulen (ᠵᡝᠩᡤᡠᠯᡝᠨ, 正古倫) and Fekulen (ᡶᡝᡴᡠᠯᡝᠨ, 佛庫倫), were bathing at a lake called Bulhūri Omo (ᠪᡠᠯᡥᡡᡵᡳᠣᠮᠣ) near the Changbai Mountains.
[5] However, another older version of the story by the Hurha (Hurka) tribe member Muksike recorded in 1635 contradicts Hong Taiji's version on location, claiming that it was in Heilongjiang province, close to the Amur river, where Bulhuri lake was located, and where the "heavenly maidens" took their bath.
This was recorded in the Jiu Manzhou Dang and is much shorter and simpler in addition to being older.
It also fits with Jurchen history since some ancestors of the Manchus originated north before the 14th-15th centuries in the Amur and only later moved south.
