陌上花开只是不在
[mò shàng huā kāi zhĭ shì bù zài]
It could mean 'Flowers blooming along the roadside (path), but just not there anymore.' This phrase might hint at missing out on something beautiful in life such as a good time or someone, even when everything around suggests otherwise - flowers blooming implies a sign of life and beauty, while 'only not there' reflects absence and nostalgia.
