I want to know the answer to the following question:
Which dynasty did Yellow Tiger declare himself the emperor of?
All the background I'm provided with is that "In the middle of the 17th century, the peasant rebel leader Zhang Xianzhong (1606–1646) from Yan'an, Shanxi Province, nicknamed Yellow Tiger, led his peasant troop from north China to the south, and conquered Sichuan.". Is that enough to answer the question?
