"Dream of Yan Yuan", also known as "Dream of Red Mansions", envisions a world-renowned higher education institution - Peking University in China - as the "Grand View Garden", thus forming a "intertextual" relationship with Cao Xueqin's "Dream of Red Mansions". "Mutual text" writing was not invented by experts. Joyce had already used it in Ulysses, but he could not have been used so skillfully and skillfully by experts. Moreover, "intertextual" writing was not invented by Joyce. David Lodge pointed out in "The Art of Fiction" that "there are various ways to refer to another text using one text: comical imitation, artistic imitation, attachment, allusion, direct quotation, parallel structure, etc." He also pointed out that the opening part of Fielding's "Joseph Andrews" is an imitation of Richardson's "Pamela.". For example, Rousseau's novel "The New Lois" clearly carries "textual referential nature".
