らくちん （楽チン）

This na-adjective wordie kind of explains itself, but this blog is for all new words and technically i didnt know this word. a new chinese study book (in japanese) i am reading said studying chinese is more "pleasent" than japanese because there is only one reading for each characterー I agree thats nice. I'm thinking they picked this adjective because it is phonetically similar to チャイナ, but maybe not. This word also means "easy going" etc.
