Tai Yai chronicles begin with the story of two brothers, Khun Lung and Khun Lai, who descended from heaven in the 6th century and landed in Hsenwi, where the local population hailed them as kings. According to tradition, the predecessor state of
Siviraṭṭha was founded before 650 AD. Hsenwi was the largest of the cis-
Salween Shan states, and at one time included all of what are now the present states of North and South Hsenwi,
Kehsi Mansam,
Mong Hsu,
Mong Sang, and
Mong Nawng. It also held
Mang Lon and other
Wa states east of the Salween •
North Hsenwi, assigned to a successful adventurer,
Hkun Sang, of
Ton Hong. •
South Hsenwi which went to
Nawmong, of the old
Shan ruling house. ==Rulers==
