What does the burial flower in Daiyu mean?

Summary of Dai Yu Burying Flowers: Lin Daiyu buried flowers for the first time because they were spent and Jia Baoyu wanted to throw them into the water. Lin Daiyu was afraid that they would flow into the gutter, so she buried the flowers. The second flower burial was the night before when Daiyu knocked on the door of Yihong Courtyard to find Jia Baoyu. Qingwen mistook it for a servant girl and refused to open the door. Daiyu misjudged Baoyu and sighed in vain that night and was angry with Baoyu. The next day coincided with the flowering period, and when I saw falling flowers everywhere, I hid from everyone and went to the place where I used to bury peach blossoms. I can't help feeling that flowers hurt myself, sighing that "today's farmers who bury flowers know their people when they are buried" and "I don't know the beauty is old in a spring, and flowers fall and people die", and I wrote the famous "Flower Funeral", which has been sadly dedicated. Baoyu was very painful when he heard this. Baoyu caught up with him and said bitterly that "what happened today must have happened at the beginning" to resolve this misunderstanding.

Burying Flowers is the representative of all the lamentations of Lin Daiyu's life experience, and it is also an important work of Cao Xueqin to shape this artistic image and show her personality characteristics. Like The Daughter of the Lotus, it is a text that the author tries to copy. This song, which imitates the style of the early Tang Dynasty, is lyrical and artistically successful.
