Sword Inscription of the Yue King in the Warring States Period Bird and Insect Seal Script

This style is similar to contemporary calligraphy, but contrary to the spirit of calligraphy. When the decoration of details in a certain art is exaggerated to the point of being cumbersome and becoming a burden, it means that the end of this style is not far away. The prosperity of regular script was in the Tang Dynasty, and the decline of regular script was also in the Tang Dynasty. This is what is called the peak of prosperity and its decline. Why did it decline? It was due to the tendency of excessive decoration.
