When the Mongols attempted to capture him, however, he successfully subdued them, and when they shouted to inquire his name he responded with a defiant challenge, "Nara".
Several generations later, two brothers among his descendants, Kesina (克什納) and Gudui Juyan (古對珠延), became the ancestors of the Hada and Ula branches of the Nara clan.
Buyan (布延), grandson of Gudui juyan, fortified the settlement on the Sungari and named himself beile of the Ula tribe.
The Yehe tribe under the beile Bujai (布齋,布戒) and Narimbulu assembled the various groups in the Hūlun alliance, along with some Khorchin Mongols, to oppose the rising power of Nurhaci.
Two years Bujantai would receive a daughter of Šurhaci as a wife, and in 1601 he arranged the marriage of his niece, the future Empress Xiao Lie Wu to Nurhaci.
