One thing I've been curious about while learning Chinese is the use of 月 in many 汉字 representing anatomical features (for example, 脸， 腰， or 腿). What is the etymology of the use of 月 as a radical?
I would like to be able to compute the distance between 2 hanzi according to their components. My idea is that a hanzi like 式 is made of 工 and 弋. 2 hanzi are close if they share common components. ...
Could someone please give we a hint when to use either of those?! My take is that 想 is used for actions and 喜欢 for things!? Am I right?
Hanzi has some underlining when dealing with foreign names, etc. What are the rules regarding Hanzi underlining? edit: Would I underline 中国 in a text that includes underlining?
