Do you have such a word or phrase in your language? If so, what does it mean? If not, are there any similar phrases? Thanks! I'm just curious. In English, it usually refers to a sentiment. There's also the phrase 'beauty is only skin deep'. Chinese: 膚淺 fūqiǎn This word usually refers to somebody's knowledge or understanding of something. For example, someone who thinks A Christmas Carol was only aimed at teaching a moral lesson might be said to have a 膚淺 fūqiǎn understanding of the novella.
