I want to know the answer to the following question:
When did Hu Yaobang visit Tibet?
All the background I'm provided with is that "Human rights organisations have been critical of the Beijing and Lhasa governments' approach to human rights in the region when cracking down on separatist convulsions that have occurred around monasteries and cities, most recently in the 2008 Tibetan unrest.". Is that enough to answer the question?
Answer: no
