Travelling from Hangzhou to Shanghai By Train - Passport needed ?

Travelling from Hangzhou to Shanghai By Train - Should i Carry Passport with me
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.

P.S : Should i Avoid Travelling now and Travel Later When i Will have Passport Near Me .

Hi,now u have to have some sort of id with u to buy tickets in china,e.g. passport,drive license,id card, I guess you can buy a ticket with a copy of your passport,without one of these stuff,they won't sell it to u.

Thank You , will Show Up my Visa Extension Receipt with my Passport Copy .
