Noun + 长 / 长 + 的 + Noun
The adjective 长 (cháng) means 'long' and describes the physical length of an object or the duration of time. It is one of the most fundamental dimensional adjectives in Chinese and can modify nouns directly with 的 or serve as a predicate. It contrasts with 短 (duǎn), meaning 'short.'
