Under the surface narrative of "e;Menghua Style"e; in Tokyo Menghua Record, there are hidden historical events of Huizong Dynasty witnessed by Meng Yuan for more than 20 years. For example, the description of Tokyo's tall and majestic city walls implies that Huizong adopted Cai Jing's advice to rebuild the outer city. The winding walls of Taizu were changed to be straight on all sides, which greatly reduced its defensive function. During the Jingkang period, when the Jinbing attacked the city, because of its straightness, the entire city wall was crumbling under one shot. Others, for example, in the imperial court ceremonies describing the Zhengdan dynasty, the Nanjiao Jitian, etc., implied the Huizong reformed ritual music, the new Dasheng Music, the reconstruction of a new three-story Jitianqiu (Qingchengzhai Palace), and the promulgation of the New Ceremony of Politics and Five Etiquetteare quite convincing as a saint. It is precisely this combination of surface and bottom narrative that Tokyo Menghua Record explores the reason why the prosperity of the Northern Song Dynasty once became a dream.
