Can I bring RMB and USD cash into china from Malaysia? and also canned food

Dina, meat (cooked or uncooked) products are not allowed to enter China. So chicken curry and meat floss can't be brought into China. However, instant noodles can be brought into China. In fact, you can find halal instant noodles in the Chinese supermarkets. As for money issue, you can bring 5000 USD or 20000 RMB in total.
