Explanation
In China, pointing directly at someone or something with your index finger is considered impolite and aggressive, as it resembles a gesture of accusation or blame. Instead, use an open hand or a subtle nod of the head to indicate direction or refer to people. This rule applies broadly across Chinese society, though younger generations in urban areas may be more lenient in casual settings.
Local Tip
When you need to indicate a person or object, gesture with your whole hand (palm up or slightly cupped) rather than a single finger.
