This fallen fairy refers to Li Bai in particular, not in general.
Li Bai chanted Jiuhuashan's poem: "Yesterday, on Jiujiang (Yangtze River), Jiuhuasheng was seen from afar, and the Tianhe River hung green water, showing nine hibiscus. I want to wave, who can keep up? You are the master, lying here in Yun Song. " Among them, the poem "Tianhe hangs green water, showing nine hibiscus" has become an eternal swan song depicting the beauty of Jiuhua Mountain.
