Yu Qian: the change of folk fortress

In the fourteenth year of orthodoxy, Vara cavalry went south, and Zhu Qizhen, with the encouragement of Wang Zhen, ventured to personally expedition. The Ming army was defeated in the civil fort, Zhu Qizhen was captured, and 200,000 elite Ming troops were destroyed.
