Christmas Holiday vacation in China

It will be cold in both of the cities and you can even see snow in Beijing.
I suggest you to spend the Christmas in Shanghai and the New Year in Beijing. Last year, I think the shows in Happy Valley in Shanghai is great and I suggest you to go this year. It is a shopping time for that city.
I stayed with my friends in Beijing for the Chinese New Year and temple fairs left me deep impression. To be honest, the activities for New Year on Jan. 1 are a few, but you still can see some. Last year, I went to Chinese Ethnic Culture Park to see the New Year activities.
