Spain and China have differences in punctuality norms. In Spain, informal meetings tend to be very unpunctual, with people arriving at varying times. However, formal meetings at work or with students respect schedules more, though people may stay later than scheduled without pay. In China, nonverbal communication differs from American styles due to a more collectivist culture. Greetings involve bowing the head slightly to show respect based on age. When agreeing informally, people use a gesture wishing for a long agreement.
