There are many osmanthus trees in Lingyin Temple in Hangzhou. Why did Bai Juyi write Jiangnan?

Bai Juyi once worked as a secretariat of Hangzhou, stayed in Hangzhou for two years, and later worked as a secretariat of Suzhou for more than a year. When he was young, he roamed the south of the Yangtze River and lived in Suzhou and Hangzhou. It should be said that he knows a lot about Jiangnan, so he was deeply impressed. Twelve years after he returned to Luoyang from Suzhou, he wrote these three poems recalling Jiangnan at the age of 67, which shows that the scenery of Jiangnan is still vivid in his mind.

What is Bai Juyi's longest impression in Hangzhou since I can't forget Jiangnan?

The ancient book says: "Lingyin Temple in Hangzhou is rich in osmanthus. The monk in the temple said,' Plant this month.' Up to now, watching the night in the Mid-Autumn Festival, children often fall, and monks try to pick it up. "Since monks in the temple can pick it, it seems that Bai Juyi deliberately picked it when he was in Hangzhou, and he also went to Lingyin Temple many times to look for Na Yue's laurel seeds, just to appreciate the osmanthus flowers on the moonlit night in Sanqiu.

Bai Juyi is a poet, and naturally he has a romantic temperament. On the moonlit night of osmanthus fragrans in August, he lingered under the moon, sometimes looking up at the moon, and sometimes looking down to see if there were laurel trees flying in the shadow of osmanthus fragrans. What a beautiful and moving picture this is. One is to find words, and emotion and scenery blend together, meaning and scenery blend together, poetic and fascinating.
