本文认为《红楼梦》是小说，红楼世界是个模拟的世界，应该按照小说的模拟化特征去诠释研究，那种把大观园当作实在园林去考证寻踪，把秦可卿当作历史人物去考证索隐，离开作者自己的交代去另觅她的出身未必寒微的方法，是不足取的，违背小说的艺术特征的。 This paper argues that “Dream of Red Mansions” is a novel, the world of Red Mansions is a simulated world, and should be interpreted in accordance with the simulated features of the novel. The kind of viewing the Grand View Garden as a real garden, the investigation of Qin Keqing as a historical figure, It is not enough to leave the author’s own explanation to find another way of her origin, which is contrary to the artistic features of the novel.
