After the Qing army entered Jiangnan, almost all the massacres were completed by soldiers in the early Ming Dynasty. Another typical example is 1650, when Wang Shangxi of Pingnan led an army to attack Guangzhou and slaughtered the city for half a month. According to the accounts of survivors and western missionaries in Guangzhou at that time, 600,000 people were killed, comparable to the "Yangzhou Ten Days". Bai Jin, a French missionary who once served in the court of Kangxi Dynasty, wrote in the book Emperor Kangxi: "In fact, in the process of conquering the (Ming) empire, the Tatars (Manchu) paid almost no price, but the Han people killed each other, and the bravest of the Han people went to fight for the Tatars against their own nation." This is the biggest failure of the Ming Dynasty and the tragedy of the Han people.
