In my opinion, to reflect the true kung fu of calligraphy, it is good to write it with biological propaganda. The most intuitive presentation of calligraphy is stippling. Both the figure and the calligrapher's style and emotion should be presented through stippling, because when we observe a work, the most intuitive is the character composed of stippling. Calligraphy has a high demand for stippling. High-quality stippling includes cone painting sand, leakage marks and Yin Yinni's reputation. There are also requirements for calligraphers' pen power, and calligraphers with strong pen power can often penetrate the back of the paper. Here we need to introduce the performance of two kinds of rice paper (raw rice paper and cooked rice paper). Familiar propaganda does not eat ink, suitable for writing small letters and drawing meticulous paintings. Eating ink for health promotion is suitable for writing calligraphy and painting freehand landscapes. Only by writing with raw materials can the ink penetrate into the paper, and the strokes will appear thick and smooth, showing high line quality. If you use familiar propaganda to write, the ink will not penetrate into the paper at all, but will float on the paper, so stippling is easy to be frivolous.
Therefore, it is incorrect to say that Sheng Xuan can't reflect the true kung fu of calligraphy.
