I. Invention of Xuan Paper According to folklore, after the death of Cai Lun, a papermaker in the Eastern Han Dynasty, he had an apprentice named Kong Dan, who always wanted to invent a peerless paper to paint his teacher's portrait, but he could not find the top materials. One day, he saw an old sandalwood lying in the middle of a stream. Although the bark has rotted and turned white, it still shows fine fibers. Kong Dan had a brainwave and thought it was an excellent material for papermaking, so he tried it again and again and finally made the world-famous Xuan paper. During the Tianbao period of the Tang Dynasty, Xuan paper was widely popular.
Second, the birth of pen and ink The origin of pen and ink is much earlier than that of rice paper. As early as primitive society, archaeologists found that pens were made of animal skins tied to wooden sticks, but the lines of pens made in this way were very rough. Later, in the bronze age, murals were born, and the appearance of murals meant the beginning of strokes. Before the Han Dynasty, the ink used mineral pigments, such as graphite or ink pigments, but in the Han Dynasty, Song Yanmo was used. Generally speaking, the color is black. The real peak of pen and ink was in Wei, Jin, Southern and Northern Dynasties.
