明史
On May 15, the Army of Qing broke through Nanjing, and the Hongguang regime was destroyed. Zhu Yujian, the clan relative of Ming founded a new court called Longwu at Fuzhou. Meanwhile, Li Zicheng, the leader of the peasant uprising army jointed with the Ming's governor He Tengjiao, and fought against the court of Qing. It was impossible to concentrate a large member of stuffs to compiling the "History of Ming" in the unstable political and embattled situation.
