Dear Sir/Madam,

My father and I wish to visit China, Beijing in particular and Shenzhen. We also would like to make a round trip by train( new train) across China to Lhasa in Tibet( so we can see the countryside from sea to mountains).
I understand tibetan visas are only issued via authorized travel agents. Can you provide me such a list or at least some links to such travel egenat?
Thank you
Amitabh
