Post and telecommunications offices open daily, often until late at night. Shops , too, nearly all open daily, keeping long, late hours, especially in big cities, and although banks usually close on Sundays - or for the whole weekend - even this is not always the case. Tourist sights such as parks, pagodas and temples open every day, usually 8am-5pm and without a lunch break. Most public parks open from about 6am, ready to receive the morning flood of shadow boxers. Museums , however, tend to have slightly more restricted hours, including lunch breaks and one closing day a week, often Monday or Tuesday. If you arrive at an out-of-the-way place that seems to be closed, however, don't despair - knocking or poking around will often turn up a drowsy doorkeeper. Conversely, you may find other places locked and deserted when they are supposed to be open.
