Why is "Geese in Chinese poetry" trending?

Wikipedia Overview

Geese are an important motif in Chinese poetry. Examples of goose imagery have an important place in Chinese poetry ranging from the Shijing and the Chu Ci poets through the poets of Han poetry and later poets of Tang poetry such as Li Bai, Wang Wei, Du Fu, and the Xiaoxiang poetry, especially in the poetry of the Song dynastic era. Various poetic concepts could be communicated by the inclusion of the imagery of geese in a poem, and the understanding of allusions to a goose or geese can help provide key insights into the poems of Classical Chinese poetry. Chinese sources typically distinguish between two types of geese, the domestic goose, and the wild goose: of the two, the wild goose is the more important for poetry, whether as significant of migratory seasonal change, or as "bearing a message of love from afar", by persons separated by a great distance, or as the "lone goose", bereft of both mate and flock.
