What is the poet's inner feelings expressed through?

The cuckoo is a modern poem by Yu Guangzhong, a famous poet in Taiwan Province.

In The Cuckoo, the poet not only expresses his sadness, dissatisfaction, disbelief and helplessness over the invasion of normal and peaceful life by modern commercial society and vulgar culture through direct and approximate satire on "beer", "barren hill" and "excavator", but also expresses his yearning and expectation for the simple and happy life in the past through the beautiful recollection of the old life in his hometown, just like people in developed countries and regions are eager to get in touch with nature now. The yearning for a simple and ordinary life, the unattainable hope, and the helplessness of hope failure. The short poetic structure fully embodies the architectural features of poetry and also shows the consistent style of Yu Guangzhong's poetry. The fast rhythm and natural segmentation make readers fully feel a strong sense of jumping when reading.

Throughout the poem, the brisk rhythm, fresh words, refined and unpretentious rhetoric, appropriate hidden feelings and looming "characters" are really like those written by poets. There is a bagpiper who plays a sad and melodious aria on a miserable cloudy day, giving people infinite reverie and vision. The above is for reference.
