"Businessmen don't know how to hate their country" is a kind of ballad. It is the admirers in that building who really "don't know how to hate their country"-feudal nobles, bureaucrats and gentry. The backyard flower, or "yushu backyard flower", is said to have been written by treacherous court official Chen Houzhu in the Southern Dynasties. This decadent voice has killed Chen Chao. However, in this declining era, some people use this voice of national subjugation for fun instead of thinking about national affairs, which can't help but make poets worry that history will repeat itself. The word "across the river" is inherited from the story of "national subjugation and hatred for the rich", which means that the Sui soldier Chen Shijiang was in Hebei, while the small court in the Southern Dynasties was in danger across the river, while Chen Houzhu was still indulging in debauchery. The word "still singing" skillfully and naturally connects history, reality and imagined future into a line, which is meaningful.
These two poems, with graceful and light-hearted style, show bitter satire, deep sorrow and infinite emotion, which can be called "farewell songs". These two sentences express sober feudal intellectuals' worries about state affairs, and also reflect that bureaucrats and nobles are filling their decadent and empty souls with singing and dancing, leading a drunken life, which is a portrayal of two different aspects in the real life of the decline of the late Tang Dynasty.
