How it's used
Although this is a four character idiom, it is frequently used in casual speech to describe someone who is insincere or manipulative. It carries a stronger sense of deliberate deception compared to simply being indecisive or shy. It is often paired with the phrase 講一套做一套 to emphasize the gap between a person's words and their actual behavior.

Common mistake
Learners often mistake this for a verb phrase, but it functions as an adjective describing a person's character or a specific instance of behavior. Do not use it to describe a simple misunderstanding or a slip of the tongue, as it implies a conscious choice to hide one's true thoughts.
