"Qi" here refers to strengthening people's moral cultivation.
"Qi" originally refers to a natural substance that constituted all things in the universe in ancient China. The Book of Changes says, "Essence is the thing." Wang Chong linked "Qi" with spiritual activities and put forward the viewpoint that "Spirit is based on blood gas" (On Balance and Death). The "blood gas" here refers to the substance and vitality that constitute the human body. Before this, Mencius also put forward the theory of "knowing friends" and "nourishing qi". Mencius explained that the "noble spirit" he cultivated was born of "supreme spirit" and "gathering righteousness" and needed "matching righteousness with Taoism"
"Qi" here refers to strengthening people's moral cultivation. Cao Pi inherited these views on "Qi" and applied them to literary theory, expounding the relationship between a writer's temperament, talent, ideological accomplishment, creative personality and work style. This is of great value to understanding literary creation, its style and achievements, and is also of positive significance to the development of literary theory criticism in China. However, it is a big limitation to overemphasize the writer's innate temperament and talent while ignoring the influence of acquired learning, including social practice and artistic accomplishment.
After a person's temperament is formed, it is relatively fixed. However, the qi in this article fluctuates, so it is more appropriate to call it "Yun Qi". In this regard, Han Yu of the Tang Dynasty emphasized it most clearly. He talked about this in his reply to Li Yishu: "Qi, water is also; Words, floating objects; When the water is big, things float and the size floats. " Qi as it says, gas as it says, is suitable for people who speak briefly and have a high voice. "In some books,' qi' is often interpreted as the author's ideological accomplishment, which is wrong. A person who has never read a book has his own anger.
If it is shown in a China work, then this work has its own spirit. For example, in a calligraphy, every fluctuation can't reveal the author's ideological accomplishment, but it clearly shows the spirit and unique rhythm in the author's heart. There are countless articles written by Han Yu in his life with different contents, but the ups and downs are interlinked, and people compare it to "tide".
After reading Han Yu's article, you can feel the surging tide, one wave after another. The so-called "Han Dynasty and Su Hai" is a concise summary of the verve style of Han Yu and Su Shi, two great essayists in the Tang Dynasty.
