Their differences are as follows: Tang poems are mainly lyrical, and even if they are reasonable, they are mostly expressed in lyrical ways; Song poetry likes reasoning and advocates discussion. Tang poetry is more implicit; Song poetry is more straightforward and poor in words. Tang poetry pays more attention to the direct description and expression of life feelings; The excellent works of Song poetry also come from life, but they are often grasped rationally before choosing the appropriate form.
