The poem "The Authentic Biography of Huai Su" written by Bai Juyi, a poet of the Tang Dynasty. According to the Chinese Ancient Poetry Network, the meaning is that Huaisu was a famous calligrapher in the Tang Dynasty. His authentic calligraphy has been handed down to this day, but his thoughts have long been scattered among the grass and trees, and he did not know when he turned into ashes. I don’t know who came here with Huaisu’s thoughts, but the dew flowers here still bloom beautifully and the branches are still luxuriant. This poem expresses the poet's admiration for Huai Su, and also expresses his emotion about time and his thinking about life. The dew flowers in the poem symbolize the beauty of life and the tenacity of life, expressing the cherishment of life and the pursuit of strength.
