(2) This kind of poem devoted to expressing feelings naturally leads to the irrationality, illogicality and thoughtlessness of the poem itself. There are no philosophical poems and aphorisms in Japanese classical poetry, and poets never take explaining and expressing certain ideas as the task and purpose of writing poems. Classical poems in China, Persia and India often argue in poems, while Japanese poems only describe a scenery or express a feeling, which is equivalent to the "comparison" and "xing" parts of China's poems.
(3) The indiscretion of Japanese poetry leads to a strong tendency of surrealism, recreation and aestheticism in Japanese classical poetry. Japanese poets have been trying to keep the distance between poetry and reality to the maximum extent. Japanese poets don't even directly disclose and reflect themselves in their poems. They think that being too close to reality will lead to vulgarity and weaken artistic value.
(4) What is associated with this rash, surreal, entertaining and aesthetic tendency is the simplicity of the subject matter. Most of the themes of Japanese poetry are nothing more than four seasons, love affairs, parting of life and death, love and entertainment, and the rest are ignored. Zhenmen Harmony attempts to expand the scope of subject matter and describe poems in daily life, but the result is vulgarization and non-artistry. It can be seen that the simplicity of the theme is determined by the unique aesthetic characteristics of Japanese poetry.
