The rule of thumb is to pack lightly, and to bring casual clothes. A sturdy, comfortable pair of walking shoes is an absolute. A sports coat and a nice shirt for man, and one or two dresses or pantsuits for women will suit the most formal occasions to be encountered in China. Travelers should bring shirts, sweaters and jackets that can be worn in layers to suit a range of climates. Shorts (for both men and women) are fine for summer days though not recommended when visiting religious shrines. Remember, dress for Comfort, not for Style.
