Hello,
I would like to visit Shanghai-Hong Kong-Beijing but somebody said me that Xiam is a beautiful place to visit so, I decided to go, but I don't know if the best way to go is from Hong Kong or from Beijing, and by plane or by train.
I readed that the cheapest way to go to Hong Kong from Sahnghai is take the plane from Shanghai to Shenzhen, then in Shenzhen what have to take?? bus, train or boat to go to Hong Kong??

Thank you very much

Esther
