左耳离心右耳离人
[zuŏ ĕr lí xīn yòu ĕr lí rén]
The name literally means 'the left ear is close to the heart, while the right ear leads to people far away'. This implies that someone's words (heard from the left side) may touch our hearts deeply, yet another’s voice just fades into air without causing any ripples in the mind (hearing with the right side), indicating selective listening according to one's own preference or emotion.
