礼节

lǐjié - etiquette

I came across this word today and recognised both characters, but not the word. This is partly because I can never remember the meaning of the second character (which, in turn, is partly because it has so many, and partly becaue I often confuse it with 带). It seemed like it might be a useful word one day.

按照礼节你应该站起来接待客人。
According to etiquette, you should stand up to meet a guest.
