It was from the Tang Dynasty poet Zhang Ruoxu's Spring River Flower Moonlit Night. Shanyue doesn't know what's in her heart Jiang Hua still smiled at the spring breeze. The spring breeze caresses my face, and the flowers dance the bright moon shines on the ditch water, naturally clear. This poem described the beautiful scenery of the moonlit night on the spring river. The poet admired the moon and spring flowers on the river at night, but he could not suppress his longing for the past. In the end, he sighed with emotion. The spring breeze caressed his face, the flowers danced, the moon shone on the ditch, the water was clear, and the things in his heart could not be forgotten. This poem expressed the emotion and longing of life that was easy to pass away and difficult to realize.
