[4] An ethnic Mongol, he was a native of Harqin Middle Banner (today Ningcheng County, Chifeng).

Some scholars read his Chinese name as a transcription of another Mongolian name Buyantai (meaning "meritorious", in Cyrillic Буянтай), and conflate references to Serengdongrub and Buyantai; however, as Christopher Atwood points, Buyantai (布彦泰) was actually another Harqin Mongol, whose Chinese name was Yu Lanzhai or Yu Lanze (??择).

[5] In 1912, he entered the Mongolian and Tibetan School at Beijing under Gungsangnorbu.

In 1934, he became a member of the Mongol Local Autonomy Political Affairs Committee.

From 1948 to 1949 he served as head of the Mongolian and Tibetan Affairs Commission.
