Weak question: Why do meticulous paintings need seals? Some even printed a lot! What role! Excuse me! I am ignorant!

A good painting, from the artistic point of view, mainly from three aspects: First, the painting itself, such as style, composition, pen and ink, color. Second, the inscriptions, such as position, font and size, are consistent with the painting itself and have a certain level of calligraphy. Third, seals, such as style, size, genre, the collocation of yin and yang seals, the position of seals, the correctness of words, the unity of calligraphy and painting, etc. Since Ming and Qing Dynasties, seal, as an important part of painting and calligraphy, has become a stereotype. A comprehensive painter should have the theory of calligraphy and painting, be familiar with calligraphy, painting and seal cutting, and be skilled in techniques. Some famous painters are like this, such as Zhang Daqian, Fu Baoshi, Qi Baishi, Wu Changshuo, Zhao and Gao. They are not only good at calligraphy and painting, but also good at printing, so the seals they use can better match their paintings and achieve more perfect harmony and unity. The seals on calligraphy and painting are mainly divided into three categories: one is the seal of the author himself. Second, the signer's seal. Third, the seals of collectors and connoisseurs. These seals are divided into three aspects: first, the name, font size, hall number and hall number seal; Second, write at will, seal auspicious words and aphorisms. Third, collect and appreciate seals.
