The scheduling of appointment is very important in western culture.
预定约会在西方文化里是非常重要的。
If you want to visit somebody or invite somebody to do something, the best way is to make an appointment with him in advance, because most westerners often keep a strict person schedule. They don't welcome unexpected visitors. Usually for a westerner three schedules are kept, one for daily events one for weekly planning and one for long term planning. You have to show respect for their cultural custom.
Often appointments are made on the phone by talking with him directly or with his secretary, who can help him to arrange the appointment. Remember to tell him or her directly why you want to meet him. Before making an appointment,you must know the full name and title of the person you want to meet. If necessary ,you can check with his secretary. All the appointments should be double-checkde for accuracy. The time, address, names of involved parties, and spelling and pronunciation of the names should be verified.
Don't be late for the appointment. You have to get to the meeting place on time. If something urgent happens which prevents you from keeping the appointment, you can change or cancel the appointment immediately. It is very impolite for you to fall to keep an appointment.
