First Ming Communication With Yunnan (1369)
The first communication between the Ming dynasty and Yunnan was in a formal "letter of instruction" using ritual language. Submission to the Ming was described as part of the cosmological order:
"From ancient times, those who have been lords of all under Heaven have looked on that which is covered by Heaven, that which is contained by the Earth and that on which the sun and moon shine, and regardless of whether the place was near or far, or what manner of people they are, there was no place for which they did not wish a peaceful land and a prosperous existence. It is natural that when China is governed peacefully, foreign countries would come and submit (來附)”…I am anxious that, as you are secluded in your distant places, you have not yet heard of my will. Thus, I am sending envoys to go and instruct you, so that you will all know of this" (14 July 1370).
