I want to know the answer to the following question:
Who aided the Yongle Emperor?
All the background I'm provided with is that "On March 10, 1403, the Yongle Emperor invited Deshin Shekpa, 5th Karmapa Lama (1384–1415), to his court, even though the fourth Karmapa had rejected the invitation of the Hongwu Emperor.". Is that enough to answer the question?
Answer: no
