Dulbert Mongolia and Moxi Mongolia in Heilongjiang are different branches. They belong to the descendants of Dovaso Hall, the brother of ben mi El Gan, the 11th ancestor of Genghis Khan. "After Doiseau's death, his fourth son didn't regard Doberman as his uncle, but abandoned him and moved to Durbert's house." They were herded in the east of Hulunbeier. Jin Dynasty, a clan of its own, migrated from the left bank of the middle and lower reaches of Nenjiang River to the right bank of Tongken River and Hulan River to Songnen Plain. Hasal, the 14th brother of Genghis Khan, who was nomadic in Hulunbeier, traveled from Hulunbeier along Taoer River and Chu Er River to Nenjiang River Basin in order to assist Dalai Sun Kudenghan. After the death of Quemontasala, his eldest son Bodida came to live along the Nenjiang River. Ai Najia, the eighth son of Baudida, led the Balujin people and lived together with the local Durbots for a long time, forming a new Mongolian tribe with the Balujin people as the main body, that is, the Durbots. This tribe has been handed down from generation to generation. 1624 (Nine Years of Destiny) Ainagaz Aduqi, together with Taijiaoba in Horqin Department, returned to Houjin. Dulbert Banner of Daqing Mongolian Autonomous County in Heilongjiang Province in Qing Dynasty.

Moxi Mongolia is one of the four departments of Erut, which was formed in16th century. It is closely related to Junggar (Qiu Ahlas). It is said that they are all descendants of Chen Yuan Khan Julos. It is now distributed in Baiyin Guoleng, Bortala, Buxair in Xinjiang and Fuxian in Heilongjiang Province, and some provinces in Mongolia also have Dulbert Mongolians living in Elute.

Heshuote, Junggar, Durbert and Turkut form a loose tribal alliance, nomadic in the vast areas north of Tianshan Mountain, south of Altai Mountain, east and south of Balkhash Lake. 1745 (ten years of Qianlong), after the death of Grdan Tsering (the son of Tsering Abadan), the nobles in Junggar fought for the position of Khan, and made great efforts to attack and kill Grdan Tsering for self-reliance. Because the Dulbert Department was "unwilling to submit to Davatchi", Davatchi and Amursa requested the neighboring Kazakh Sultan Abilayhan to send troops to attack the Dulbert Department. /kloc-in the summer of 0/753 (18th year of Qianlong), Abilayhan dispatched 5,000 soldiers and launched a fierce attack on Dulbert's department, which caused unprecedented havoc to Dulbert. At the national conference, the leaders of Dulbert, led by Che Ling, clearly put forward that "it is not a tactic to rely on Junggar, but it is better to return to China as a long-term solution", so in the winter of 1753 (the eighteenth year of Qianlong), more than 3,700 families belonging to it broke free from the bondage of Junggar and left the Irtysh River, which had been nomadic for many years, and moved to the mainland. The Qing government "learned to split the banner into two" for Dulbert, and officially named it as Dulbert's son Yatu League. After the Qing government unified Wulianghai, Dulbert was moved to Wulan for nomadism, and Wulianghai was nomadic in Cobdo. Since then, Dulbert's department has settled in Wulan, Gumu.
