High speed bullet train from Beijing

There is no G-train from Peking to Tianjin. You could take C-train, the intercity train, which only takes about 30-40 minutes. You need to take it at the South Train Station. There is also no high speed train or bullet train to Chengde from Peking, only ordinary trains leaving from the railway station. Well, there is high speed train running from the south railway station to Shanghai which only takes around 5 hours. There are many nice attractions in Shanghai, such as the Bund, Huangpu River Cruise, The Oriental Pearl Tower, Yuyuan Garde, Nanjing Road, Qibao Ancient Town, Shanghai Old Street, etc. It is worth visiting.
