A: Rhetoric is used.
Does "tail connection" mean a vast area? "Before the loop" is still the height of Mount Tai. "Square territory" is territory, and "arrogance" is squinting. Who says vast territory and abundant resources are boundless? I looked left and right, and it was all in my eyes. The poet does not directly say the height of Mount Tai, but that the scenery of the earth is in front of him, which is more advanced and diverse than the previous direct description. Meanwhile. These two poems also skillfully use the meanings of Mencius' "Climbing Mount Tai and Being Small in the World" ("Mencius' Dedicated Articles") and "Climbing to the top, you can see at a glance that other mountains are dwarfed under the sky". "(Du Fu's Wang Yue), these are all natural and innovative.
