What does the tension between overseas Chinese literature and modern and contemporary literature mean?

Tension, the original meaning is the power of water surface to make water droplets condense into a circle without spreading. Similarly, poetry has tension, which shows that the whole poem has a strong sense of cohesion to the central point. For example, for oak trees, it is a poem with tension.

Defamiliarization is also called abnormality and strangeness. Actually, it refers to the alienation effect of artistic expression. People always repeat some habitual and mechanical expressions in daily language use, and poetry can give rhetoric a fresh and unfamiliar feeling by interrupting this semantic connection, and enhance the artistic effect of works by increasing the difficulty and time of feeling.

A few years ago, modern abstractionism was inexplicably prevalent, and laymen followed suit. They wrote that the donkey's lips are not the horse's mouth, so tension can be used to measure whether the central theme of poetry is clear or not, and whether it deviates from the utilitarian category of the theme in some sentences.
