Appreciating Zhang Yisheng's only two poems, he was "isolated and for everyone" because of "A Moonlit Night on a Spring River". The philosophy of life contained in this poem, like a strong emotion coming at you, has fascinated countless literati and poets for thousands of years. No wonder, this poem was praised by Mr Wen Yiduo as "a poem among poems, a peak among peaks". This poem not only depicts a beautiful moonlit picture by the river, but also shows rich and delicate emotions. However, it is particularly important that this emotion is also permeated with rational thinking, that is, thinking in love. Faced with such a beautiful picture and the most touching beauty reflected by the five objects on the riverside, perhaps it is really "joy begets sorrow". The clear universe of heaven and earth has aroused the poet's reverie and meditation: "Who saw the moon on the riverside first?" When did Jiang Yue take the photo at the beginning of the year? "Jiang Yue is so beautiful, and the wonderful scenery can't help but remind people of the profoundness and eternity of the universe, thus linking their own lives with such smallness and brevity. Who stood by the river and was the first to be surprised by the bright moonlight? In what year did the bright moon shine on the river? I'm afraid no one can tell. After all, human life is too short, too short! If people want to race against time, they will eventually fail, and life is really easy to pass. Isn't the eternal change of human beings from generation to generation a manifestation of the shortness of life? The bright moon is similar every year. Why is this month the same every year? Perhaps, just like people who have left this world, they are waiting for the arrival of their loved ones! "I don't know who Jiang Yuezhao is. "Here, an anthropomorphic technique is used to write the moon with great feelings. In order to meet the person she expects, it can last forever. The poet looked up at the moon and down at the river. What a short time it is! " The deceased is like a husband; Don't give up day and night ",life, people's youth is not sent away by this turbulent current? From the infinity of time and space to the limitation of life, the poet feels mysterious and cordial, showing a deeper and broader sense of the universe. Similar moons and images of different people hide the poet's short-lived grief over life, which runs through the whole poem and creates an artistic conception with endless charm. However, the key of the whole poem lies in the description of Sifu in the second half, who is unhappy because she is looking forward to seeing her lover. But she still believes that although they are separated from each other and can't hear each other silently, at this time, they will definitely miss the bright moon. There is a famous saying in Qiu Ge's Song of Midnight at Four o'clock in the Southern Dynasties: lifting myself to look, I found that it was moonlight, send acacia by the moon. In this poem, the feeling of trust in the moon is changed to "May the moon shine on you", which is more intense and urgent. The word "chase" here makes the deep, persistent and passionate feelings about women more vivid, concrete and vivid, and gives readers a distinct sense of movement. It can be seen that although there is a brief sadness about life in the poem, it is only out of love and pursuit of life, and the poet has not been decadent and desperate. Its keynote is "sadness without injury", which reflects the aspirations of the early Tang Dynasty. Of course, due to the limitations of the times and classes, this poem also has some shortcomings, and it has not completely got rid of the influence of formalism in the Six Dynasties. However, the profound feelings expressed by many colorful images in this poem are also frightening, especially the understanding and appreciation of life sentiment can arouse readers' deep thinking and sentiment. This is also the performance of the poet's superb skills, combining scenery with reason perfectly, creating a new artistic conception and giving people a new understanding and feeling.
