The classical Chinese novels about fairy tales in the Qing Dynasty often use allusions,which is quite different from the narrative-focused recording methods in the previous dynasties.Through the repeated use,hidden use and reverse use of allusions,the reconstruction of knowledge has been realized,mak-ing the classical Chinese novels about fairy tales in the Qing Dynasty have an obvious tendency of knowledge writing.This is related to the prosperity of flo-ral dictionaries in the Qing Dynasty and the style of floral dictionaries that fo-cuses on the dictionary.It can be said that floral dictionaries provide neces-sary knowledge support.Knowledge writing promotes the classical Chinese nov-els about fairy tales to have a unique aesthetic effect,and knowledge counter-point is the key to decoding the code.Analyzing the citation situation of clas-sical Chinese novels about fairy tales in the Qing Dynasty can further investi-gate the evolution process of classical Chinese novels that gradually leave the"Ministry of History"and have obvious creation characteristics.
