暮光薄凉蓝了夏天日光倾暖白了冬天
[mù guāng bó liáng lán le xià tiān rì guāng qīng nuăn bái le dōng tiān]
This nickname has a lyrical tone to it, evoking imagery and sentiment connected to twilight making the summer appear blue with slight sadness (凉 can mean 'cool' but in this context, 'a touch cold'), while sunlight in winter creates whiteness. In essence, expressing mixed emotions through season-based metaphors.
