What are the requirements to get a China visa if my mom will pay for the whole trip?

I dont a have work right now. Im only taking care of my husband's business. My mom will send us to Beijing for a short trip. She paid for our ticket and hotel and will give us pocket money. I dnt have my ITR n SSS contributions has stopped. What papers do i need from my mom to prove that she will pay for the expenses? By the way, she will not be joining us. The trip is more of a gift to us.
