Jia-jing: Year 39, Month 3, Day 28
23 Apr 1560
Initially, the chieftain Mang Da-la of Ava-Burma in Yun-nan had harboured a grudge because his forbear [Mang] Ji-sui had been killed by the Meng-mi native official Si Zhen and the Meng-yang native yi Si Lun, and he wanted to take revenge. Subsequently, Si Zhen's son Si Han died and there was contention for succession between the sons of primary and secondary wives. Mang Da-la made use of the confusion and took Si Han's second son Si Zhuo as a son-in-law and sent him back to Meng-mi to seize the seal of his elder brother Si Song. Subsequently, he used Meng-mi as the route by which to attack and plunder the various yi of Meng-yang and Yi-xi to revenge old scores. Then he had Zhuo-ji of his gang invade and occupy the territory of Meng-mi. Subsequently Zhuo-ji was killed by Si Zhen's son-in-law, the Meng-nai chieftain Bie-hun. Da-la was angered and personally led his troops to attack Bie-hun and his son, and captured them. He also incited the three native offices of Long-chuan, Gan-yai and Nan Dian to rebel. However, through spies he came to know that defence preparations had been made and, also worrying that other yi might invade his territory, he fled home. At this time, the Grand Defender Mu Chao-bi and other officials memorialized on events. The Ministry of War stated: "The way of the Emperor in governing the yi is to punish the rebellious and pardon the transgressions of those who submit. Now Da-la has felt fear of the Imperial might and withdrawn to the distance. The Court need only display its grace and might so that he will make a new beginning. Special instructions should be sent to the various native yi noting that they are not permitted to have communication or form associations with each other. In this way, the distant territories will be naturally at peace." This was approved by Imperial command.
