Ceramic art and calligraphy art also pay attention to and emphasize the expressiveness of lines. In the aspect of artistic characteristics, it seems to be irrelevant to ceramic art at first sight. In fact, there are striking similarities between the two.

       From the perspective of aesthetic characteristics of calligraphy art, it is an art that unifies practicality and artistry, reproduction and performance, form and lyric. It is colorless and brilliant with pictures, silent and harmonious with music, coming from and far away from the natural image. People turn their spiritual meaning, life sentiment and aesthetic taste into vertical or vertical lines, dry or moist lines, thick or thin lines, rigid or soft lines, and reflect people's aesthetic experience through the dry and moist, thick and thin personality factors of these lines. "In the process of modeling, the author's feelings and strokes are integrated together, and the pen everywhere, no matter the long-term and short-term, the short-term point and the block expanded by the point, all become the traces of emotional activities.". Ancient Chinese aestheticians had a brilliant discussion on this characteristic of calligraphy. Yang Xiong of the Han Dynasty said in fayan: "words, the voice of the mind; books, the heart painting.". Cai Yong said in the treatise on the pen: "those who write are scattered. In the Tang Dynasty, sun Guoting thought that calligraphy art could show the emotion of calligraphy artists, that is, "reach their emotion, form their sorrow and joy", "Xizhi wrote Leyi, which was full of emotion, while painting praise, which was concerned with novelty," Huangting Jing ", which was strange and nihilistic, and" Taishi Zhen ", which was also full of disputes. And in Lanting, they gathered together, thinking about the ease and the transcendence of the gods; and in private, they swore, and were in a state of distress. The so-called parties involved in music laugh and sigh. In Qing Dynasty, Liu Xizai was even more unconventional: "a writer writes his own records", "calligraphy is like learning, like talent, like ambition, like a person in a word".

       Ceramic artists, perhaps from this comparison, get a deeper and more complete understanding of the characteristics of ceramic art, so as to strengthen the expressiveness and lyricism of ceramics and create works with more aesthetic strength and value.
