I want to know the answer to the following question:
When was Chosrje Shākya Yeshes sent to Nanjing?
All the background I'm provided with is that "Rossabi writes that Tsongkhapa did not want to entirely alienate the Ming court, so he sent his disciple Chosrje Shākya Yeshes to Nanjing in 1414 on his behalf, and upon his arrival in 1415 the Yongle Emperor bestowed upon him the title of "State Teacher"—the same title earlier awarded the Phagmodrupa ruler of Tibet.". Is that enough to answer the question?
Answer: yes
