Mr Arsalan, are you going to China for business purpose? Do you have an invation letter from your supplier? If you don't have, you can just apply for L visa instead of F visa. Submit the following documents:
1)An actual passport, which must have at least 6 months validity before expiration.
2)A duly-filled visa application form
3) Round-trip flight tickets and hotel reservation
4) Bank statement of your recent three months
