Cao Cao (155-0315,220) was born in Peiguoqiao County (now Bozhou City, Anhui Province). China was an outstanding statesman, strategist, writer, calligrapher and poet in ancient times. At the end of the Eastern Han Dynasty, Quan Xiang was the son of Qiu Cao Song and the founder of Cao Wei.
On one occasion, Cao Cao entered Zhang Rang's mansion and tried to assassinate him. Zhang rang sent someone to hunt him down after he found out. Cao Cao came out of the hall waving ju. Zhang rang's guards couldn't get close to him. Cao Cao fought and retreated. When he retreated to the wall, he jumped out and jumped over it.
After pacifying the north, Cao Cao felt "bereavement" out of pity and nostalgia for his old friend Cai Yong, so in the eleventh year of Jian 'an (AD 207), he sent messengers to redeem his daughter from the Xiongnu land in the north and remarried to Chen Dongsi, and asked her to sort out more than 400 books left by Cai Yong, which made a side contribution to the spread of Chinese culture.
