Origin: Boating in Guazhou is a seven-character quatrain written by Wang Anshi, a writer in the Northern Song Dynasty.
Original text: Guazhou, Jingkou, is a water room, and Zhongshan is only separated by several mountains. Gentle spring breeze blowing green again, but, the moon in the sky, when you can take me home?
Standing at Guazhou Ferry, looking south, there is only a Yangtze River between Jingkou and Guazhou, and Zhongshan, where I live, is hidden behind several mountains. The warm spring breeze has once again blown the fields in the south of the Yangtze River green. When will the bright moon shine on me and return to my home under Zhongshan Mountain?
Extended information:
Creation background: Boarding Guazhou was written in the late period of Wang Anshi, in the first year of Xining, Song Shenzong (168), and Wang Anshi was called to Beijing from jiangning house to be a bachelor of Hanlin, and then passed through Guazhou.
The first sentence in the poem reveals a relaxed and happy mood by writing about the short distance between Jingkou and Guazhou and the fast speed of the ship. In the second sentence, the poet looked back at Zhongshan, where he lived, and felt reluctant to part; The third sentence describes the Jiangnan scenery full of spring; Finally, it ends with a questioning tone, once again emphasizing the yearning for my hometown. The whole poem is not only lyrical by scenery, but also full of emotion in narration, with an open realm and fresh style.
The sentence "When will the bright moon shine on me?" In terms of time, it is already night. The poet looked back for a long time, but he didn't realize that the red sun was setting in the west and the bright moon was at the beginning. Although the scenery across the bank disappeared in the hazy moonlight, the attachment to Zhongshan deepened. He believes that he will throw himself into the old mountain forest one day, so he expresses this idea in a rhetorical way at the end.
The poem's scenery description at the beginning not only has a comparative interest, but also forms a powerful contrast between the proximity of space and the length of time through exaggeration, which almost leads to the emotional generate of "when the bright moon shines on me" at the end, which is likely to be broken at first.
