Coming from someone who learned Japanese first:

-Chinese practice of creating slurs by adding 鬼 to the name of a race/occupation/etc (e.g. 黒鬼, 酒鬼, 鬼佬) unintentionally makes the thing you're trying to disparage sound cool as hell

-Chinese practice of using 子 as a nominalizing suffix to create a handily parseable two-character compound (e.g. 靴子, 梅子、瓶子) unintentionally makes random nouns look like Japanese women's names
