对于你我何必用情至深
[duì yú nĭ wŏ hé bì yòng qíng zhì shēn]
'There Is No Need To Love So Deeply For You' suggests feelings of unrequited love, regret, self-reflection, or a realization about past intense emotions dedicated to another person. This implies the speaker has learned that it's not always wise or beneficial to invest such depth of feeling into someone.
