In China's traditional culture, hanging characters also have a unique meaning. We often hear the word "listening to politics behind the curtain", which means that the emperor shows that he is listening to the opinions or reports put forward by ministers or important officials by listening to politics behind the curtain in the harem or inner hall. The practice of listening to politics behind the scenes originated from the founding emperor in ancient times and continued until the Ming and Qing Dynasties, becoming a standardized political ceremony.
In addition, hanging characters also plays an important role in China's calligraphy. China's traditional calligraphy emphasizes the change and fluency of strokes, and verticality is one of the indispensable elements in China's calligraphy. Vertical strokes are often used to express the overall structure and sense of stability of a word. Usually, we can see the use of vertical strokes in some calligraphy works to enhance the overall effect of writing and create a solemn atmosphere.
