Good day!
I already have my tourist visa for China just for 10 days, I will be leaving here on the 23rd of July to go to China Shanghai Airport. Now I wanted to know if there's any other documents that I need to bring upon entering the Airport here to fly for china. Do I need show money? If so, how much would it be? I was invited a friend of mine that is working in china to visit him there, so definitely I didn't booked to any hotel's there as my friend has an apartment wherein I can stay while I'm there for 10 days, Do I need to bring the invitation letter? Address of the apartment of my friend? His ID? or what should I be needed to bring?

Please.. can someone help me for this.. I only have few days to go...
