他夏了整个夏天她暖了整个冬天
[tā xià le zhĕng gè xià tiān tā nuăn le zhĕng gè dōng tiān]
'He filled an entire summer; she warmed an entire winter' compares two significant others whose presences have had opposite yet meaningful influences. One might recall fondly about passionate days in hot weather and warm nights under cold conditions brought by those loved ones respectively.
