I want to know the answer to the following question:
Who helped the Tibetan?
All the background I'm provided with is that "When the Dzungar Mongols attempted to spread their territory from what is now Xinjiang into Tibet, the Kangxi Emperor (r. 1661–1722) responded to Tibetan pleas for aid with his own expedition to Tibet, occupying Lhasa in 1720.". Is that enough to answer the question?
