Hello All , I will Be Travelling to Shanghai from Hangzhou by Train in Some days , But the thing is I Have my Passport with me now , But the Day i will Be Travelling My Passport will be with Exit & Entry Administration Dept. In Order for my Visa Extension .

I need to know 2 Things ...

1. Can i Travel with out My Passport ? ( I will Keep Passport Copy for Safe Side & I Will Also have the Receipt Given by the Dept. that i Had Submitted my Passport and When i will be Receiving my Passport .

2. Can i Book a Ticket Without Passport ( I Dont Know Any Local Chinese People Here to Use There ID Card).
Or I can Book a Train Ticket by the Copy of My Passport and the Receipt of the Dept.
