After Si Xingfa, Si Renfa was enthroned in 1413, and he tried to restore the kingdom to its former glory. In 1439, a conflict between Mong Mao and Ming reoccurred. This was the beginning of the Luchuan–Pingmian campaigns. In 1441, Ming sent troops to Mong Mao, and Si Renfa fled to Mongyang. Several wars occurred between 1443 and 1449, and finally Mong Mao lost Dehong. The imperial family continued to live in Mongyang until they were attacked in 1604 by the Toungoo dynasty.
