通衢

通衢 refers to a major or main road, often used metaphorically to describe a central or important path, route, or channel of communication or transportation.

The character 通 (tōng) means 'to pass through' or 'common,' while 衢 (qú) originally referred to a crossroad or intersection. Together, they form a term that emphasizes a central, well-traveled route.

通衢 is often used in both literal and figurative contexts, such as describing a city's main street or a key pathway in a broader sense, like a career or life path. It appears in classical literature and modern Chinese to emphasize importance and accessibility.
