First we are a few days in Suzhou. Then we leave for Zhangjiagang (by taxi). We stay three days in Zhangjiagang. Then we will go to Beijing. What's the easiest way? Order traintickets in Suzhou for Beijing? Is there a bus from Zhangjiagang to Suzhou? Maybe first by bus from Zhangjiagang to Shanghai and then take the train? Or take a bus to Wuxi and than take a train? I really have no idea. This will happen in July.

Thank you!
