My family will be visiting Beijing 10 Sept ~ 17 Sept 2011. What type of clothes should we bring?

Beijing will be in cool autumn during the middle of Sep. Generally, the weather is mild with sunny days and cool night. You should wear long-sleeved shirt and jeans. A thin jacket should be taken in case of cool night and morning. On the other hand, it will also be dry in autumn, so remember to drink enough water. Anyway, it is a nice time to visit Beijing.
