About allusions
Allusions originally referred to old systems and old rules, and were also the official names of those in charge of historical facts such as the ritual and music system in the Han Dynasty. A later common meaning refers to stories or legends about historical figures, regulations, etc. The name Allusion has a long history. It can be traced back to the Han Dynasty, "Book of the Later Han Dynasty." "Cang Zhuan of Dongping Xianwang": "I personally bow down to the supreme, pay tribute to my subordinates, give banquets every time, change the appearance of the banquet, worship personally in the middle palace, allusions have happened."
Allusions refer to the system and the Anecdotes. "Cihai" and "Ciyuan" establish two meanings for the word "allusion": First, the ancient meaning of the word allusion is somewhat equivalent to the "allusion" in modern Chinese, which refers to ancient regulations and systems, old events and practices. Of course, the allusions we are talking about today use the modern meaning of allusions. The modern meaning of allusion is explained in "Modern Chinese Dictionary" as "stories or phrases in ancient books quoted in poems". The interpretations of "Cihai" and "Ciyuan" are similar to this, saying that they are "ancient stories and words with provenance quoted in poems."
