思君使人老我已千百岁
[sī jūn shĭ rén lăo wŏ yĭ qiān băi suì]
'Si Jun Shiren Lao Wuoyiqian Baisui' expresses deep longing and sorrow for missing someone, metaphorically aging due to this yearning. In English, it conveys feelings like 'Longing makes me grow old; I'm a thousand years old because of missing you.'
