requirments for visa for a family member without bank statement

My Uncle and Aunt are going to the Canton Fair and they want to tag me along. They were required with bank statement and other requirements. I do not have a bank account that can suffice the requirement of 120 thousand daily average. Can I they just sponsor me since they will be the one who is going to shoulder my expenses? What's the easiest way to get it? Should I just get a Tourist visa instead?
