Suzhou, Shanghai and Nanjing are nearby cities around Hangzhou, which can be easiy reached by bus or train (including bullte train). Xian, Guangzhou and Fujian (which city in Fujian, Xiamen, Fuzhou, Wuyishan or Quanzhou?) is a bit further. It takes over 20 hours from Hangzhou to Xian by train and takes more time to Guangzhou. Xian is snowing now, not heavy just a little. You can consider to come by train from Shanghai. THere are more comfortable trains from shanghai. Fly to Guangzhou, I suggest.
