魑魅魍魉 - demons; bad people. Good for practising that 鬼 radical I guess. I like the look of this one, anyone found any other interesting chengyu?

对牛弹琴

I spent a summer in Texas on 40 acres of land. In the morning while I was practicing, the cows would wander up to my front door to listen.

Though I loved the attention, the chengyu suggests I was wasting my time with them...

人山人海

Good one if you're in China :)

What does mean chenyu?

Chinese idiom, usually 4 characters long. Often associated with long and meaningful stories / legends.

hey murrayjames

that 成语 is that one I always said I would use as my 艺名 if I ever decided to move around China as an artist ;)

A 成语 I've always liked was 百发百中...and well...my "name" on skritter is obviously based on that chengyu (you may have three guesses as to what that says about my retention rate^^)

nice cheng yu, the problem with these is there is no way you can really deduct the meaning if you do not know it before hand.
