Three traitorous calligraphers in Chinese history
Although Cai Jing, Qin Hui, and Yan Song can be called masters of calligraphy, they are Because of their evil deeds, their calligraphy was abolished, so very few calligraphy works have been handed down.
Cai Jing, a native of Fujian, was the leader of the "six thieves" during the reign of Emperor Huizong of the Song Dynasty. He colluded with Tong Guan, the imperial minister, to threaten Song Huizong and overthrow the Song Dynasty. Towards the abyss of disaster. Cai Jing's calligraphy is unique. Even the arrogant Mi Fu once said that his calligraphy is not as good as Cai Jing's. At that time
The Cai of "Su Huang Mi Cai" originally referred to Cai Jing. Later generations hated his treachery and changed his name to Cai Xiang.
Qin Hui, a native of Jiangsu, killed the national hero Yue Fei and insisted on surrendering. He was a famous traitor during the Southern Song Dynasty
Huizong. He was a scholar, erudite and accomplished in calligraphy. Based on
imitating Huizong Zhao Ji's "thin gold style" font, he created a neat, uniform,
simple Yi Xue's unique font was used to write memorials, and even Emperor Huizong of the Song Dynasty ordered the whole country to write official documents according to Qin Hui's model font. This font gradually evolved into "Song style" for printing.
Yan Song, a native of Jiangxi, passed the second-level imperial examination at the age of 25 and has profound calligraphy skills. Later, he joined the party for personal gain and harmed the loyal and good. In the end, he was reduced to the people and his family property was confiscated. His family property was confiscated to the extent of more than 30,000 taels of gold and 2 million silver. Two, equivalent to the country’s total fiscal revenue for one year at that time.
It is said that the three characters "Zhigongtang" on the plaque of the Gongyuan Hall of Shuntianfu Rural Examination in the capital of the Qing Dynasty were written by Yan Hao, the traitorous official. Emperor Qianlong wanted to replace it. When he lost it, he ordered all the people in the court who could write to write these three characters.
He also wrote several times himself, but he felt that his imperial pen and the characters written by others were different.
None of them were as good as Yan Song, so I had to give up and still let the character of the treacherous minister Yan Song hang high.
