Tang Luzong's "Reading Commentary" said: "Huaisu's cursive script can be changed at any time with the help of millimeters. Zhu Changwen's "Continuation of Book Break" of Song Dynasty listed Huaisu's calligraphy as a wonderful product. The comment said: "If The strong man draws his sword, his appearance is moving. "
Mi Fu's "Haiyue Book Review": "Huai Su is like a strong man wielding a sword, with a moving spirit, and he is always turning forward and retreat, without missing the mark. ”
Cursive screen Tang Hanzi
Where is the screen, clearly traces of ink.
Although it is dusty and stained, there are still thick ink marks.
Strange rocks rush into autumn streams, and ancient pines hang on cold vines.
If you were to teach me to write by the waterside, I would be afraid that every word would become a dragon.
Huai Su is good at using the center strokes to express his will. The momentum is like a big grass, like "a sudden rain and whirlwind, the sound of the hall is full", to the state of "suddenly three or five screams, filling the wall with thousands of words". Despite his speed, Huai Su was able to fly through the entire story with very few mistakes.
