四衢（巨俱反爾雅路四達謂之衢郭璞交道四出者也釋名云道四達曰衢齊魯之間四齒把為衢衢把地則有四處此道似之因以為名）。

Crossroads (衢: *gju-kju* [fanqie: 巨俱]. The Erya says: 'A road leading in four directions is called a crossroads (qu).' Guo Pu says: 'Intersections branching four ways.' The Shiming says: 'A four-way road is a qu. In Qi and Lu, a four-pronged rake is called a qu; when a qu rakes the ground it leaves four marks. This road resembles it, hence taking the name').
