2. Understand the background: Wang Lun, also known as LAM Raymond, was the magistrate of Jingxian County during the reign of Tang Kaiyuan. After leaving office, I lived in Taohuatan, Jingxian County. From the first year of Tianbao (742) to the first year of Baoying (762), Li Bai traveled to Dangtu, Xuancheng, Jingxian, Qiupu, Nanling and other places in Anhui many times, and visited Taohuatan in Jingxian. He entertained his guests with wine. When he left, Li Bai wrote, "Li Bai visited Taohuatan from Qiupu (now Guichi, Anhui) to Jingxian (now Anhui). Wang Lun, a local, often entertains him with homemade wine. When he left, Wang Lun came to see me off again, and Li Bai wrote this poem to leave.
3. Determine whether the writer should use the poet's brushwork, Wang Lun's point of view, or the point of view of a third-party bystander. Of course, it is best to use the poet's point of view.
