那个夏天太阳也曾哭过那个冬天月亮也曾笑过
[nèi gè xià tiān tài yáng yĕ céng kū guò nèi gè dōng tiān yuè liàng yĕ céng xiào guò]
Translating as 'In that summer, the sun once cried, in that winter, the moon also smiled', this reflects a person’s mixed emotions about past seasons and experiences – happiness in one period, but possibly pain in another.
