1, calligraphy and painting can prevail, which is the product of the liberation and freedom of human nature in the times. Produce an artistic climax.
2. The style of calligraphy and painting is also influenced by metaphysics. It also laid the style of literati painting and calligraphy.
3. The influence of Buddhist art and beautiful scenery in the south of the Yangtze River cannot be ignored.
4. Famous painters and painters emerged, and the Eastern Jin Dynasty inherited their ethos from the Western Jin Dynasty.
5. Large-scale application of paper.
