When was Bai Juyi's Memory of Jiangnan written?

Recalling the beautiful scenery in the south of the Yangtze River, I was once familiar with the sunrise, and the Red River triumphed over the fire. When spring comes, the river is as green as blue. Can you not remember Jiangnan? For Jiangnan, Bai Juyi seems to be just a passer-by In the second year of Changqing (822), Bai Juyi became the secretariat of Hangzhou. In May of the fourth year of Changqing (824), Bai Juyi returned to Luoyang, the eastern capital, and was appointed as Suzhou secretariat the following year. He was exempted from county affairs due to illness and returned to Luoyang after taking office for more than a year. From this point of view, Bai Juyi only stayed in Suzhou and Hangzhou for more than three years, not too long; Bai Juyi's hometown is in Henan, and Jiangnan is just the place where he is an official. Even if he leaves, I'm afraid it won't arouse his thoughts about sea bass. However, why does Bai Juyi have such a deep attachment to Jiangnan? Bai Juyi was relegated to Jiangzhou for four years and finally returned to Beijing in the fifteenth year of Yuanhe. This seems to be God's compensation for his bumpy career. Bai Juyi, who has just returned to Beijing, seems to be very excited. "When you get water, you get fish, but you still have scales, and when you get cranes, you get long." He once said, "A gentleman keeps the way and treats others. It's time. It's Yunlong and Peng Feng. Suddenly, Chen Li came out. " Perhaps, at this time, Bai Juyi thought that he had finally waited for his own time. However, the battle between cronies in the imperial court is still fierce, and political traps are always waiting to be eaten with their mouths open. Bai Juyi lamented: "If you have high worries, there will be traps." The shadow of the Wu incident has been entangled in Bai Juyi's heart. Afraid of being persecuted by powerful people again, he dared not stay in North Korea for a long time and volunteered to go abroad. As a result, the beautiful Jiangnan suddenly met a frustrated poet in the ninth century. Presumably, when Bai Juyi left Beijing, it was also a general mood of throwing birds into the forest, right? Away from the land of right and wrong, away from the struggle of officialdom, the poet came to paradise on earth. This is not a wild place where the house is full of bitter reeds and yellow rushes, nor is it a dangerous vanity fair, but the most relaxing resort of "circling the lotus for 30 miles and blowing thousands of pines all over the city". Bai Juyi once introduced the beautiful scenery of Hangzhou to friends: The guests asked Hangzhou to stop drinking for me and meet you briefly. The mountain name Tianzhu heaps indigo, and the lake name Qiantang flows green oil. There are many geese's teeth under the big eaves, and there are faucets painted on the boats. Without 300 waterways, why do officials have to swim again? Joy is beyond words. For Jiangnan, Bai Juyi is actually a returnee. Bai Juyi boasted in his early years, hoping to use words to accomplish his great achievement of "being the most monarch, being Yao and Shun, and then making the customs pure". However, the ups and downs of official career are tantamount to giving the poet a blow. After living in Jiangzhou, my previous ambition seems to have disappeared. Some commentators said that Bai Juyi gradually became depressed. If only poetry looks good, in Hangzhou, Bai Juyi, an official, found another more practical way to realize his ambition. As soon as he took office, he encouraged himself that "Suzhou and Hangzhou have been famous counties since ancient times and are now good officials." When he was in office, he organized people to build water conservancy projects. In order to prevent floods, he presided over the construction of dams. In order to commemorate Bai Juyi, later generations called this dam "Baigong Dike". At this time, Bai Juyi has completed the transformation from a scholar who guides the way to a down-to-earth official. Facing the people who lived and worked in peace and contentment under his rule, the poet said with satisfaction, "Everyone is happy and travels thousands of miles at night." Perhaps it was at this time that Bai Juyi wrote the famous Spring Tour in Qiantang. From the north side of Gushan Temple to the west side of Jiating, the lake is just level with the embankment, with low clouds and waves on the lake. Several early orioles raced to the sunny tree, and their new swallows were carrying mud in their nests. Colorful spring flowers will gradually fascinate people's eyes, and shallow spring grass can barely cover the horseshoe. I love the beauty on the east bank of the West Lake, and I can't get enough of it, especially the white sand embankment under the green poplar. As an official, Bai Juyi linked himself with Jiangnan and the people of Jiangnan. So, in this way, the poet returned to Jiangnan, no longer a passer-by, but a returnee from Jiangnan. Hundreds of years later, another poet who was an official in Hangzhou followed Bai Juyi's footsteps and continued to walk in the world. After Bai Causeway was in disrepair for a long time, he presided over the construction of a dam called "Su Causeway", which was also a way to pay tribute to his respected former poet. This latecomer is Su Shi. In the fourth year of Changqing (824), Bai Juyi returned to Beijing at the end of his term. Except prince Zuo bastard, Shi Dongdu. Bu lives in Luoyang Road. After being an official for more than 20 years, he couldn't get enough money to buy a house, so he had to pay it back with two horses, which shows that he is an honest official. Since then, Bai Juyi has been an assistant minister of punishments, but after leaving Jiangnan, he is no longer willing to be an official. Perhaps, on a sunny morning, the dying poet will still think of those green mountains and green waters, the place where there is no power, no tricks and no frame-ups, the place that really belongs to him. Then, secretly ask yourself: "Can you not remember Jiangnan?" Attachment: Jiang Nanyi is the other two novels of Bai Juyi's Memories of Jiangnan, and Hangzhou is the most unforgettable one. Looking for laurel trees in Zhongshan Temple in the month, watching the tide on the pillow in the county pavilion. When will you revisit? Jiang Nanyi, followed by martial arts; Wu Yi cup of spring bamboo leaves, Wu Wa dance lotus drunk. We will meet sooner or later! Note: ① According to Biography of Hans Zhang in the Book of Jin, Hans Zhang, a native of Jiangnan, was an official outside. As soon as he saw the autumn wind, he missed the shepherd's purse, shepherd's purse soup and perch in his hometown, so he said, "The important thing in life is to make yourself comfortable. Why wander thousands of miles just to win fame!" So he abandoned his official position and returned home. Later generations say that they don't want to be an official, and the feeling of missing their hometown is called "thinking of perching."
