Number + Classifier + Noun
Chinese numerals (一, 二, 三, etc.) are used in various contexts including counting, ordering, and literary expressions. When numbers appear in sequence, they can convey a poetic or enumerative effect. For example, 一去二三里 uses numbers in a classical verse to describe distances.
