Question: What are standard business office hours?

Answer: In China, standard working hours are usually 08:00 to 17:00 or 09:00 to 18:00. Major shopping malls open from 08:30 or 09:00 and close around 21:00 in winter and 22:00 in summer. Because traffic is especially congested during rush hour, tourists are advised to avoid peak-hour traffic at 07:00 to 09:00 and 17:00 to 19:00. Many educational, some working offices and small businesses may close during the lunch hour which extends from approximately 11:30 to 13:30.
