The writing technique of borrowing ancient poems in articles is called Yongdian.
Yongdian means to use things, and is often seen in poetry. Quote stories or words from ancient books as allusions. Can express relevant content and thoughts richly and implicitly. Quoting allusions.
Liu Xie explained "Yongdian" in "Wen Xin Diao Long", saying that it is "based on events to make meanings, and to refer to the past to prove the present." That is to say, it is used to compare the past with the present, to prove the present with the past, and to express feelings through the past. The use of allusions must not only follow the meaning, but also be able to seek new ideas from the past, and more importantly, it must be able to make it look like it has come out without leaving any trace. As the saying goes, "Salt is in the water, and you will know the taste of salt when you drink the water" before it can be a good work.
