China's calligraphy art from spontaneous to conscious stage marks the arrival of this period.

The development of China's calligraphy art was spontaneous before Wei and Jin Dynasties, and began to enter the conscious stage after Wei and Jin Dynasties. The development of calligraphy art in China is accompanied by the development of characters, and the two complement each other, as shown below:

1) Two stages of the development of calligraphy art. Since there was writing, there has been calligraphy. China's calligraphy is an ancient art, which develops with the development of Chinese civilization. Calligraphy embodies the basic characteristics of China art, just as architecture and sculpture dominate other kinds of plastic arts in western art, so calligraphy and painting dominate other kinds of fine arts in China, ranking first in China. Putting calligraphy and painting together puts calligraphy in front of painting, which is called "painting and calligraphy", such as "painting and calligraphy are of the same origin", "Qin Qi painting and calligraphy", "painting and calligraphy" and "being able to write and draw" and so on. In the world, there are only a handful of nationalities with calligraphy art, and China's calligraphy has a long history. The textbook introduces two stages of the development of China's calligraphy art. Before Wei and Jin Dynasties, it was basically a spontaneous stage, and Wei and Jin Dynasties began to enter a conscious stage. Since then, the aesthetic function of calligraphy has surpassed the practical function, and consciously creating the beauty of calligraphy has become an art form with China cultural characteristics.
