Even during the mourning period, Zheng Qiao didn't put down his research. When Zheng Qiao 16 was in Zheng Qiao, his father fell ill in Suzhou. So Zheng Qiao took his father's son back to the countryside, buried him under Wang Feng, and erected a monument. A thatched cottage was built next to his father's grave. During the mourning period, he studied while mourning. After the mourning period, Zheng Qiao had no money to buy books, so he had to borrow books from his home by the stream with dry food on his back and classify them, thus completing a bibliography.
Zheng Qiao wanted to abandon his pen and join the army, but the court turned a blind eye to it. Nomads from the invasion of the court, Zheng Qiao and his younger brother Zheng Houman came to Bianjing from their hometown with patriotic enthusiasm, and Bianjing wrote twice to defend the motherland and resist the invasion of Nomads from the army. However, at that time, the imperial court had been attacked by the tourist trap of the nomads from there, and advocated making peace with them and compromising with them. Naturally, the court will not pay attention to the Zheng Qiao brothers. After Zheng Qiao's patriotic enthusiasm was broken, he decided to give up the imperial examination.
Zheng Qiao gave up his official career to concentrate on his research. After Zheng Qiao entered the official career from his brother Zheng Hou, Zheng Qiao lived in seclusion in the mountains and decided to write Tongzhi to inherit China culture. After Zheng Qiao finished reading, he wanted to give a book to Song Gaozong, but because some officials were jealous of Zheng Qiao's talent, he lost some skills to stop him. Finally, Zheng Qiao died of overwork.
