invitation and support letter

Hi, a friend of mine invited me to visit Guangzhou China this August,He sent me his invitation letter, together with a photocopy of his chinese ID and bank certificates since he 'll be responsible for all of my expenses and accommodation including round trip airfair.My question is ,do I still need my own bank certificate/account statement? I dont have work certificate and ITR because I'm unemployed.Is there a possibility for me to be granted a tourist visa?

I hope someone can answer my questions .

Thank you so much
