Jiangnan is good, and the scenery is familiar to me.

When the sun rises, the flowers on the river are as red as fire, and when spring comes, the river is as green as blue. How can we not remember Jiangnan?

The translation is as follows:

Hello Jiangnan, I used to be so familiar and understanding of the beautiful scenery of Jiangnan.

Whenever the sun rises from the east, the sun shines on the earth, and the flowers blooming everywhere are more beautiful. The spring water is blue and the green waves are sparkling. How can such a beautiful scenery make me not recall Jiangnan?

Extended information:

Bai Juyi once served as the governor of Hangzhou, staying in Hangzhou for two years, and later served as the governor of Suzhou, with a term of more than one year. In his youth, he roamed the south of the Yangtze River and lived in Suzhou and Hangzhou. He had a good understanding of the south of the Yangtze River, so the south of the Yangtze River left a deep impression on him. When he resigned from the post of governor of Suzhou due to illness and returned to Luoyang for more than ten years, he wrote these three poems "Recalling Jiangnan".

The specific time of writing the lyrics has always been said in different ways. Some say it was after Bai Juyi left Suzhou; some say it was in the third year of Kaicheng (838); some say it was in the first year of Yamato (827); Wang Guowei said it was written in the "89th year of Yamato". These statements are general and simple and lack factual basis. Liu Yuxi once wrote several lyrics to "Recalling Jiangnan", which were sung with Bai Juyi, so he said in the preface: "The lyrics for He Le Tian Chun are based on the beat of "Recalling Jiangnan"."

This is The poems were composed in Luoyang in the early summer of the second year of Emperor Wenzong's reign (837). From this, it can be inferred that the three poems written by Bai Juyi should also be written in the early summer of the second year of Emperor Wenzong's reign.
