花心被人骂执心被人刷
[huā xīn bèi rén mà zhí xīn bèi rén shuā]
The meaning here is: If you are flirtatious (fickle-hearted), you will be scolded by others; If you keep firm devotion to love (perseverance-hearted), your feelings might be taken advantage of by others or remain unnoticed. It indicates two extreme sides of dealing with love.
