UK student applying for Visa to china in Korea

Hi there,
I am a UK student who is in korea on a tourist type and am planning to visit mainland PRC through pudong airport for one weekend while I am in Korea, I was wondering if these are the all documents I would need to submit and I have a few questions about some of them:

1)Application for Entry for Visit/Transit in Hong Kong (ID 1003A)

2)Recent photograph (affixed on page 1 of the application form ID 1003A)

3)Photocopy of passport

4) Photocopy of financial standing proof, e.g. bank statements, savings accounts passbooks, tax receipts, etc. and proof of employment (if any), e.g. company leave letter, salary slips, etc.

Q-Does this mean there is a minimum amount of money I must have when applying, If I was mainly using cash right now would I need to put that money back into my international bank account and obtain a bank statement

5)Photocopy of proof of transportation arrangement, e.g. flight itinerary

Q-Is this just a copy of the 2 way flight ticket journey?

6)Photocopy of proof of the proposed leisure visit to Hong Kong, e.g. receipt of joining a package tour to Hong Kong, itinerary, etc.

Q-I am going to meet a friend and stay with him for the 2 days I am there, how would I be able to prove that?

Hopefully you can tell me if all these requirements are correct and answer my questions about the documents I am unsure about so I can apply as soon as possible,

Thanks in advance
