Introduction to calligraphy and painting of the past dynasties: Chinese calligraphy and painting are an important part of Chinese culture, with profound traditions and unique national styles. Chinese painting can be divided into "meticulous brushwork" and "freehand brushwork". Figures, landscapes, and flower-and-bird paintings are the three major categories of Chinese painting. During the Five Dynasties, the Palace Painting Academy was born; in the Song Dynasty, "literati painting" was born. As a result, the Chinese painting world has the distinction between folk painting, literati painting and academic painting; Chinese calligraphers in the past dynasties showed their talents in calligraphy styles such as Zhen, Cao, Seal, Li and Xing, giving birth to many calligraphy schools.
