I want to know the answer to the following question:
Who believed the Ming reappointed old Yuan dynasty officials in Tibet?
All the background I'm provided with is that "Norbu writes that, although this would have been true for the eastern Tibetan regions of Amdo and Kham's "tribute-cum-trade" relations with the Ming, it was untrue if applied to the western Tibetan regions of Ü-Tsang and Ngari.". Is that enough to answer the question?
