Pack lightly, and bring casual clothes. A sport coat and tie for men and one or two dresses or pant suits for women will suffice for most formal occasions. When packing accessories, decide what's really important and take only the items you'll really use. Today's China is well-stocked with most personal items, although you may prefer to take along your favorite brands. Don't forget to take along a travel alarm, a good travel guide, and a map.
Most hotels have a hand hair-dryer in each room.
