I want to travel to Beijing/Shanghai in the winter/early spring of 2007. However, Chinese New Year (Spring Festival) begins Feb. 18 and travel will be crazy. There are many crowds & full hotels as it is a business/school holiday and Chinese people will travel to visit family. I would really like to avoid this hectic period. Will waiting 1 week (Feb.25) be enough for crowds to go down and return to work, or should I wait until about March 10 or March 15?
