All these things can be taken into China, but the amout are strictly limited. For the wine, you cannot take over 1.5L with degree under 12. For milk powder, you can only take 8 cans if one can holds 800g and take 24 cans if one can hold less than 800g.

For other food, you can only take some for your personal use, otherwise you may need to pay for them if you take a lot.
