良人怎知情深
[liáng rén zĕn zhī qíng shēn]
'Liang Ren Zen Zhi Qing Shen' means 'How Can a Good Person Know How Deep Love Is?'. It suggests that even someone who is kind and decent may not fully understand the depth or complexity of love. It highlights the idea that true love can be incomprehensible even to virtuous individuals.
