Liu Xizhai, a Qing Dynasty man, praised Chu Suiliang's calligraphy as a "broad educator". The late contemporary great calligrapher Shen Banfu studied Chu calligraphy, saying that Chu "can bring forth the old and bring forth the new in the Tang Dynasty", and pointed out that Chu Suiliang was "a descendant of the two kings, a teacher of the master's spirit and a willful teacher", which spread to Yan Zhenqing and opened up a brand-new avenue in the history of calligraphy.
Emperor Taizong was the Duke of Henan, and the world called him "Chu Henan". Bo dabbled in classics and worked in Li Kai. After Yu Shinan's death, Emperor Taizong sighed: "After Yu Shinan's death, no one can talk to the author!" Wei Zhi recommended Chu Suiliang, saying, "Chu Suiliang's hard writing has won a lot for Wang Yi." Emperor Taizong Bao loved Wang Xizhi's calligraphy and gave him gold and silk. At that time, Wang Shu was sent to Beijing, and it was difficult to distinguish between true and false. Only in this way can you judge and identify, and catalog and hide it within the government. His calligraphy inherited Wang Xizhi's tradition of being soft outside and rigid inside. His skillful brushwork is more important to the world. He, Ou Yangxun, Yu Shinan and Xue Qi are also called "four great masters in the early Tang Dynasty". During the reign of Emperor Taizong, he was very tired as a living lang, an admonisher, an official and a secretary.
After Tang Gaozong ascended the throne, Chu Suiliang was demoted for trying to prevent Tang Gaozong from making Wu Zetian the queen, and died on the way to being demoted at the age of 63. In the years after his death, Wu Zetian did not forgive him, not only stripped him of all his official positions, but also exiled his descendants to distant places. However, Yonghui's rule and opposition to the establishment of Empress Wu Zetian made Chu Suiliang's reputation immortal. Won the admiration of later literati.
