I want to know the answer to the following question:
Who told the emperor that the situation in Dbus and Gtsang were under control?
All the background I'm provided with is that "According to Chen, the Ming officer of Hezhou (modern day Linxia) informed the Hongwu Emperor that the general situation in Dbus and Gtsang "was under control," and so he suggested to the emperor that he offer the second Phagmodru ruler, Jamyang Shakya Gyaltsen, an official title.". Is that enough to answer the question?
Answer: yes
