In the late Ming and early Qing dynasties, Gu Yanwu loved reading stories about loyal officials and righteous men since he was a child. He took part in a revival society and organized a garrison commander to fight against the Qing Dynasty in Kunshan. After the city was broken, he kept in mind his stepmother Wang's teachings and stopped being a courtier of the Qing Dynasty, so he disguised himself as a businessman and traveled around to unite with anti-Qing people from all over the country. He wrote in the "Rizhilu": "Those who protect the world are cheap and have no responsibility."

national difficulties are added later.
