When a Chinese person hands you a knife, they will do it blade first, not hilt first as we're accustomed to in the states. It feels weird to just grab a knife by the blade.
The reason enough Chinese people are handing me knives for me to comment on it--you peel every single fruit you eat here (almost). Pears (of which there are a ton of varieties) and apples always get peeled; I think it's because people don't like eating the skin, but I'm not exactly sure so I just follow suit.
My Mom, who despaired of my inability to properly peel an apple when I was trying to help her make apple sauce (I went for lots of hacking rather than proper technique), will be pleased to learn that my peeling abilities are masterful and getting better.
