The word 升高 (shēnggāo) is a compound verb formed by combining two individual characters, each with its own meaning, to create a new, more specific concept. The first character, 升 (shēng), means "to rise" or "to ascend", while the second, 高 (gāo), means "high" or "tall". Together in a verb-complement (or verb-resultative) structure, the word literally means "to rise high", where the action of "rising" directly results in the state of being "high". This formation efficiently conveys the process of an increase in height, level, degree, or status, whether referring to temperature, prices, or one's position.
