In my opinion,it's OK to buy foreign food.Different countries have dfferent culture and different kind of food.We should accept different cultures.There's no reason for us not to buy foreign food.If you like it,just buy and eat it!Just like what the foreigners do.They also eat Chinese food as well.
大概就是这样吧,因为不是很明确这个问题的争论点在哪.
