This is a little joke. The original text is: An electric welder opened an electric welding shop and chose a tall shop name: Emperor Wu of Welding. Everyone praised this shop for its good name; He is also very proud, showing off everyone.
On this day, he went to the candy store next door to show off, and the owner of the candy store took him to look at his shop name: Tang Taizong, the welder was silent. The owner of the candy store pointed to the name of the cake-cutting shop not far away: Han Gaozu, and they were silent together.
The dung digger rode past the two men on a dung cart. When they looked at the dung cart carefully, they immediately blushed with shame. There are three big characters written on the dung cart: the emperor who catches excrement.
Behind the homophonic stalk
The Chinese nation has an implicit and restrained aesthetic pursuit, and in literature and art, it also advocates "the literary style is profound and profound, and the aftertaste is rich" (Wen Xin Diao Long Hidden Show). People will put the real meaning they want to express in the depths of the language, pay attention to the implication, and focus on the meaning outside the text.
Chinese homophonic art just embodies this implicit and restrained aesthetic interest. For example, in poetry, "Qing" harmonizes "emotion", "silk" harmonizes "thinking" and "lotus" harmonizes "pity". In particular, it is related to survival and future development, such as "profit", "harm", "luck" and "fierceness".
