Kingdom of Dali
Si Kefa engaged in repeated raiding on neighboring chieftainships and in 1348-49 the Yuan court sent an expedition under Marshall Dashibadu to put an end to it. The expedition failed to subdue him, but Si did send his son Mansa to the Yuan court to offer allegiance. The "Baiyi Zhuan" reports that while Mansa "accepted the Court's calendar and offered tribute, his clothing, paraphernalia and system remained like those of a king." Both the Mong Mao and Hsenwi chronicles provide lists of the far-flung domains he is said to have controlled reaching to the border of the Kingdom of Dali in the north, Xishuangbanna to the south, Burma to the east, and Yongchang to the west.
