伤风听雨
[shāng fēng tīng yŭ]
This can be perceived as a rather lonely or introspective state of mind. '伤风' (feeling ill) paired with '听雨' (listening to rain) conveys a sentimentally gloomy experience – being under the weather and only accompanied by the sound of falling rain, probably in isolation, possibly reflecting on one's mood and solitude.
