Can explain the reason for writing poetry. The preface to "Huanxisha ◎ and Mr. Liu Yazi" says: "1950 National Day, Mr. Liu Yazi improvised Huanxisha because of its rhyme."
It can express the background and mood of writing poetry. For example, Chen Yi said before the poem "meiling three chapters": "1In the winter of 936, Meishan was besieged and I was injured for more than 20 days. I couldn't get it off, so I got three poems and put them under my clothes. Spin out. "
You can summarize the main events in the poem. For example, Bai Juyi's poem "Selling Charcoal Weng" has a small preface: "Miyagi also." The so-called palace market is that the court sent eunuchs to the market to buy goods, extorting and robbing people's property at will. The poem describes the painful experience of being plundered by charcoal sellers.
Can summarize the story in poetry. For example, the preface to "Peacock Flying Southeast" reads: "Liu, the wife of a petty official in Lujiang House, was sent by Zhong Qing's mother and vowed not to marry. His family forced him to drown. When Zhong Qing heard about it, he hanged himself in the courtyard tree. When a person is injured, it is poetry. "
Can express mood and theme. For example, Jiang Kui's "Yangzhou Slow ◎ Huaizuo Du Ming" prefaces: "Xi Chun Shen Bing went to Japan and gave it to Weiyang. At the beginning of the night snow, the wheat is looking forward to it. Entering the city, you will look around for depression, cold water is green, dusk is rising, and corners are sad. I feel sad from it and feel sorry for past lives, because I am watching this song. The old man in Yan Qian thinks there is a kind of "separation" sadness. "
The preface can also explain the time and place of writing and so on.
In addition, when we understand the poetry text with the help of preface, we should also actively learn the language of preface. A good preface, the language is extremely concise, summarized and enlightening. Some prefaces, because of their profound thoughts, subtle and beautiful language and strong artistry, can be written separately, so that the poems that rank them are ignored. Among the literary corridors in China, the most famous one is the preface in Peach Blossom Garden Poetry written by Tao Yuanming, a famous poet in Wei and Jin Dynasties. The preface to the poem has been widely known for thousands of years, but the original poem has not been particularly favored by people and has faded out of people's field of vision.
