“False Friend” with “Girl”: Do not treat “丫头” as a direct synonym for the neutral English word “girl.” The default, neutral word for “girl” in Chinese is
女孩 (nǚhái). While you can say “That girl over there” (“那个女孩”), you cannot say “那个丫头” when referring to a stranger. Using “丫头” implies a pre-existing, close, and hierarchical relationship.
