I want to know the answer to the following question:
Which empire did Xiang Liang and Xiang Yu rebel against?
All the background I'm provided with is that "Kuaiji Commandery was the initial power base for Xiang Liang and Xiang Yu's rebellion against the Qin Empire which initially succeeded in restoring the kingdom of Chu but eventually fell to the Han.". Is that enough to answer the question?
Answer: yes
