I want to know the answer to the following question:
Who did the Hongwu Emperor send convoys to?
All the background I'm provided with is that "Instead of recognizing the Phagmodru ruler, the Hongwu Emperor sided with the Karmapa of the nearer Kham region and southeastern Tibet, sending envoys out in the winter of 1372–1373 to ask the Yuan officeholders to renew their titles for the new Ming court.". Is that enough to answer the question?
Answer: yes
