Father Zhu was a scholar in the late Ming Dynasty. In the second year of Qing Shunzhi (1645), he resisted the Qing army and defended Kuncheng. The city was breached and he threw himself into the river. Zhu day and night wailed and was in pain. When his brother used white brocade, he was still young. He was from a business background. He served his mother at the upper level and raised his siblings at the lower level. It was extremely difficult to prepare for the move. Don't go back to your hometown until the situation stabilizes a little. Wang Pou, who worships twenty-four filial piety, never sat in the west in memory of his father Wang Xiu, and climbed the Babel on his father's grave and changed his name to White Deer. Zhu Yongchun has never been an official. He has been teaching in the countryside all his life, attending primary schools for scholars, recording recent thoughts and so on. For teaching, I wrote dozens of textbooks in plain code. He devoted himself to the study of Zhu Cheng's Neo-Confucianism, advocated that knowledge and practice should go hand in hand, and put it into practice. Kangxi, Xu Fang and Yang are also known as "Three Masters in Wuzhong". In the thirty-seventh year of Kangxi, before he left, he said to his disciples, "Learning lies in life, and career lies in loyalty and filial piety."
He is the author of the Book of Changes, Notes on Four Books, Notes on the Spring and Autumn Period and Five Dynasties, Sleepiness Record, Shame Collection and No Confusion Record.
