I want to know the answer to the following question:
What was the initial power base for Xiang Liang and Xiang Yu's rebellion?
All the background I'm provided with is that "Under the Later Han, control of the area returned to the settlement below Mount Kuaiji but authority over the Minyue hinterland was nominal at best and its Yue inhabitants largely retained their own political and social structures.". Is that enough to answer the question?
Answer: no
