Dear MS Judy/sara,Please note that we need agent only in Yiwu and Gangzuho for the disussion of price etc, we donot need agent for traveling/tours purpose.
Our flight will arrived in Beijing and then after one day of city tour we will leave for Shanghai and Hangzhou and then to Yiwo, we need to purchase shoes and children garments in yiwu and than goes to Gangzhou for the purchasing/searching of garments. After that we will leave for Shenzhen for some official signature and move to Hong Kong also for official tour.
We need price/fare by train or plain for these cities, I think from Beijing to Shangahi and Shangai to Hangzhou fast G train/D train available.we just need to comperssion of air fare and train fare and which one is better as per your experience.

Thanks and waiting for your reply.
