He was the eldest son of Šarhūda of the Gūwalgiya clan, which belonged to the Manchu Bordered Blue Banner.
In 1660 he reported a complete victory over the Russian troops under Afanasy Pashkov (d. 1664, founded Nerchinsk in 1658) at the village of Gufatan (古法檀) which was in the Shilka River region.
In 1661, upon the discovery that Bahai had purposely omitted troop losses in this battle in his reports, he was deprived of his hereditary rank of baron.
In 1673, he was rewarded for his success in organizing a tribe of natives called the Meljere into 40 companies known as the New Manchus (新滿洲), as a result he was given a minor hereditary rank five years later.
In 1676 he removed his headquarters to a city west of Ninguta, called Kirin, and from 1682–83 took part in the preparations for attacking the Russians at Albazin.
