Hu Guoxing summarized his calligraphy theory as follows:
Knot and brushwork are two basic elements of calligraphy. Cursive calligraphy is the profound realm of calligraphy. The structural form of the structure refers to the characters, which should be standardized, in place, graceful and comfortable. The writing method of brushwork pointing and drawing should be solid, full of charm and clean. You must be able to turn your wrist with your heart, turn your pen with your hand, move in all directions, and stand out from all sides. There should be changes of rigidity, reality, astringency, dryness, Fiona Fang, straightness, frustration, retraction, attachment, echo and rotation, full of charm and rhythm, and there is no floating pen and failure. Brushwork is calligraphy. The brushwork is calligraphy. Without brushwork, it is not calligraphy, but writing.
