I want to know the answer to the following question:
Who did Rolpe Dorje send as envoys to court in Nanjing?
All the background I'm provided with is that "Rolpe Dorje, 4th Karmapa Lama (1340–1383) rejected the Hongwu Emperor's invitation, although he did send some disciples as envoys to the court in Nanjing.". Is that enough to answer the question?
