I was talking with a friend of mine in 武汉 the other day. She said even though 武汉 is such a huge city, she could still find places to escape all the noise. She used the following chengyu: 闹中取静。 She said it means to find peace within a chaotic environment. I think it's a beautiful chengyu, but I'm not really sure how to use it in a sentence. Can someone give me an example please? :)
