What kind of artistic conception and feelings does Han Yuefu's poem Jiangnan express?

Jiangnan can pick lotus, and lotus leaves are sweet. Fish are frolicking among the lotus leaves. Fish hits the lotus leaf east, fish hits the lotus leaf west, fish hits the lotus leaf south, and fish hits the lotus leaf north ②. Note 1 Tian Tian: Lotus leaves floating in water. (2) These four sentences are clearly written about fish swimming, which is a metaphor for the friendly play between young men and women in the process of labor. Appreciating and reading Jiangnan, a folk song of Han Yuefu, we can easily think of a famous story in Zhuangzi Autumn Water, and we can't help but sigh that their aesthetic experiences are so similar. The story says that Zhuangzi and Keiko are good friends. One day they are playing by the water. Zhuangzi said: "It's so happy to swim around in the water like a fish!" Keiko asked, "If you are not a fish, how do you know the happiness of the fish?" Zhuangzi retorted, "You are not me. How do you know that I don't know the happiness of fish? " Later, he declared, "I know the city above." Logically speaking, Zhuangzi is obviously sophistry in this argument. Because as a human being, Keiko can understand that human emotions and fish cannot be linked; But his mistake lies in measuring perceptual activities with rational logic. Key words Zhuangzi has said: He realized the happiness of fish from the feeling of Haruki on the water, that is, self. This involves some aesthetic and psychological problems. When people observe the movement of external things, they often produce corresponding imitation activities in their hearts, or project their emotions on this thing, and through repeated communication, they can reach the realm of unity of things and me. For example, when we watch the goshawk gliding in the air, we will have a smooth, carefree and balanced sense of movement in our hearts, so we feel that the eagle has become our own incarnation, as if we are flying freely in the sky. This phenomenon is called "internal imitation" and "empathy" by aestheticians. In addition, some psychologists also pointed out that certain exercise patterns and rhythms can directly trigger corresponding emotions. For example, a person may not dance when he is happy, but he can breed happy emotions in the rhythm of dancing. Only in this way can we understand Zhuangzi's "Fish Fun". Whether a fish is really happy or not is unknown, but it swims briskly and freely in the water, but it can cause a similar sense of movement in the hearts of fish watchers. The form and rhythm of this action are pleasant. In the sensory world where man and fish are integrated, fish seems to be happy. So say Jiangnan. This poem belongs to harmony lyrics in Yuefu classification. "Harmony Song" was originally sung by more than one person, so some scholars think that the following four sentences are harmony. Judging from the structure of the poem, this possibility is great. In any case, the first three sentences are the main body of the poem, and the last four sentences are only the third sentence, "fish play between lotus leaves", which plays a role in rendering and contrast. The three sentences in the main part describe the scenery of picking lotus in the south of the Yangtze River, which actually focuses on expressing the happiness of lotus pickers. At the beginning, "Lotus can be picked in the south of the Yangtze River, where is the lotus leaf?" First, a picture of a bright green leaf and a boat passing by is introduced to readers. He Tian Tian reveals a sigh and praise tone, which is emotional in itself. Although there is no writing about people, people are already among them. It reminds us that people who pick lotus flowers will naturally play with such beautiful scenery. What's more, the work of picking lotus is always done by young girls. Usually it is tense, but now it is like a bird out of the cage, in droves, happy and lively, naturally like water. However, the poem was stirred up here, but it stopped writing and turned into "fish play between lotus leaves." "Play" is for fun. After the first two sentences, there should have been someone's "play", but the author passed it on to the fish's "play", which is a manifestation of empathy. But although it is about fish, the artistic conception of "playing" comes from the last two sentences. Therefore, you don't have to think clearly about what is hidden here, but you can appreciate the interest of lotus pickers by intuition. However, this is not a metaphor or symbol. The "fish play" is also a real scene and a part of a complete picture. Lotus pickers are happy. Seeing groups of fish suddenly coming and going, it seems to be as lively and free as fish. At this point, the poem has been written. The last four sentences only spread "between the lotus leaves" to the east, west, south and north of the lotus leaves one by one. However, without these four sentences, the whole poem would be boring. Because the function of poetry mainly lies in moving readers with beauty. However, the sentence "Fish frolicking among the lotus leaves" is more meaningful than description, and it is also a lonely sentence, which really cannot create a rich atmosphere enough to impress readers and must be rendered in the last four sentences. These four sentences are really childish and magical. First, simply write down the east, west, north and south, but let you see a group of fish suddenly coming and going, light and lively. Second, this simple repetition creates a vivid sense of rhythm. Therefore, the images and emotions of poetry are not only presented through the meaning of language, but also flowed out in the rhythm of language. If you remember that this is a song and the last four sentences are chorus harmony, this feeling is even stronger. Third, a simple and complete melody, after chanting, will form a self-repetition in people's feelings and will last for a long time. Therefore, with these four sentences, the school of fish and the lively and brisk lotus pickers are vividly displayed. More importantly, on the reader's side, feel the picture image and music rhythm embodied by language. It seems that in his heart, there are also a group of vibrant fish playing freely. He couldn't help sighing like "Zhuangzi on the City": "This fish is really happy!" So he became a fish, a lotus picker. This is how feelings are communicated and integrated.
