What does the collective dispatch of dragonflies symbolize?

1: Dragonflies are given the symbolic meaning of autumn resentment in spring, but it is mostly because of the relationship between dragonflies and their hostess. Dragonflies and mistresses frequently appear in the poems of palace grievances, and their grievances have been fixed and extended to their noumenon, that is, dragonflies have also been included in the category of palace grievances.

2. Dragonfly never represents a fixed emotional image in poetry. It is completely controlled by the poet's mood. Whether it is joy or sadness, it is completed in the poet's "one thought difference". In the eyes of poets such as Du Fu, Chen Ziang and Pi Rixiu, dragonflies represent a leisurely and pleasant pastoral image, while in the eyes of Yuan Zhen, Du Mu and Li Shangyin, dragonflies are covered with a layer of sadness and even sadness.
