[2] Uriyangqadai, the son of Sübedei, along with Kublai and Wang Dezhen, commanded more than 100,000 soldiers marching south and conquered the Dali Kingdom in Yunnan in winter 1253–1254.

He and his son Aju, spent years in the region to pacify local Yunnanese tribes and receive the surrender of Dali King Duan Xingzhi in 1255.

[3] Having Yunnan pacified under Mongol rule, in the autumn of 1257, Uriyangqadai addressed three letters to the Vietnamese king Trần Thái Tông demanding passage through to southern China.

The Vietnamese senior leaders were able to escape on pre-prepared boats while part of their army was destroyed at No Nguyen (modern Viet Tri on the Red River).

[8] The Yuan Shi tells the initial aftermath of the battle: Chechegtu disobeyed the command, and as the Southern tribes were defeated, they could mount on their ships and disappear.

Rijiong (Trần Nhật Cảnh) asked to surrender, and for this occasion, he instituted an official for the ceremonial offerings of wine.
