Why do Chinese paintings need to be stamped with idle seals?

Several reasons: First, Chinese painting developed into Ming and Qing Dynasties, and paid more and more attention to the overall aesthetic feeling. Therefore, calligraphy, poetry and seals have gradually become a trend. Seals are divided into name seals, collection seals and leisure seals. The name stamp and the collection stamp will not be mentioned here. Leisure chapters are generally used in empty places such as corners of paintings. First, as an ornament, it balances the picture and enriches the aesthetic feeling. Second, it can also reflect the painter's personal aesthetic pursuit from the seal on the leisure chapter.
