That's not true. Because some allusions are true. Allusions originally refer to the old system and old examples, and are also the official names of people in charge of the ritual and music system in Han Dynasty. Later, a common meaning refers to stories or legends about historical figures, laws and regulations, etc. Names and allusions have a long history. It can be traced back to the Han Dynasty. The Book of the Later Han Dynasty "Wang Cang Chuan Dong Ping Xian" said: "I bow to the supreme, and I bow to the courtiers. Every time I give a banquet, I will change my appearance and worship in the palace. This is an allusion. "
Using allusion is a rhetorical device, that is, using things. Quoting stories or words from ancient books is a classic. You can express relevant content and ideas in a rich and implicit way.
