What is the weather like in Beijing, Shanghi and Hong Kong starting on Feb. 6th and running until about the 22nd. We would like to go to Beijing first but have been told that the weather there in early Feb. is really cold and we would not be able to really see any outdoor sights comfortably. We could skip Beijing and go to Shanghi and then Hong Kong for a wedding on Feb. 20th. Please reply soon. I need to make plans. We are a couple in our 60's. Thanks so much.
