天若有情天易老地若无情早灭亡
[tiān ruò yŏu qíng tiān yì lăo dì ruò wú qíng zăo miè wáng]
Originates from classical Chinese literature describing natural laws surpassing human emotions. Heaven doesn’t age despite having feelings, whereas earth would perish if it had no emotion. It is also a phrase that can express deep affection.
