if it is pure 垃圾, why does 洋垃圾 come to China? You don't want 垃圾 from Thailand, do you? China does not produce enough of 垃圾 itself?

for 88, why did the Chinese "吃洋虧"? don't they got cheated? don't they assume it is good in the first place? (Please save all your body waste for yourself and i don't want see a dirty kid here - irrelevant to the question!)

Know anything about the meaning "connotation" of a word?

Hope this helps.
