Tips
usage
衢 is a literary word for a big road that branches in all directions. You will meet it in 通衢 ('a major thoroughfare') and as the city name 衢州 in Zhejiang.
行 is the road radical. It wraps the character: its left half is written first, then the phonetic, then its right half last. Originally a picture of a crossroads, it carries the core meaning 'road'.
