Hong-wu: Year 21, Month 1, Day 19
26 Feb 1388
As Siam had come to offer tribute, some people of Yong-jia County in Wen-zhou purchased gharu-wood and other products from the envoys. At this time, there was a strict prohibition on contacts with foreign yi. People of the village made a report of this occurrence and the Provincial Surveillance Commission advised that the offenders should be executed in public. The Emperor said: "Yong-jia is situated on the route by which the Siamese come. The people traded with the envoys because they passed through. This is an ordinary occurrence and is not to be equated with having contacts with foreign yi. Release them."
