Can i bring x.o hennessy, champagne & red wine in China as check-in baggage?

Wine can be taken to CN but it should only be put in the check-in luggage.
If the alcohol is lower 12 degrees, there is no limitation in amount. But if taking much of it, you still need to declare. For the spirits, the declaration is needed when the amount is more than 1.5L and you also need to pay the tax.
