你的夏至不挽留我的冬至不守候
[nĭ de xià zhì bù wăn liú wŏ de dōng zhì bù shŏu hòu]
Translates into: 'Your summer solstice does not linger, my winter solstice is not waiting.' Here it refers to missing each other out by timing as one person's significant event (here symbolizing climax of life events or memories) do not overlap with others' meaningful moments.
