It seems like the Chinese words I should learn I have a hard time with, but the strange useless ones stick in my brain. Like WanJiaJiaJiu "Play House", like little kids playing house. Today the word came up in our class-room dialog, we were learning words having to do with time, like "When I was a small child..." Apparently kids in Korea, Japan, Taiwan, and America all "play house" when they are small, it's a global phenomenon. But at the same time: "Big Person" means adult, but "Small Person" means "bad sneaky person," so you never know what's the same and what's different.
