How it's used

This character is extremely rare in modern spoken Cantonese and is almost exclusively encountered in formal, literary, or historical contexts. It is rarely used as a standalone noun in daily life, where people would almost always prefer 邊界 or 界限. Using it in casual conversation will likely confuse native speakers as it sounds archaic or overly poetic.
