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 "The Hongwu Emperor also entrusted his guru Zongluo, one of many Buddhist monks at court, to head a religious mission into Tibet in 1378–1382 in order to obtain Buddhist texts.". Is that enough to answer the question?
