要走便走绝不强留
[yào zŏu biàn zŏu jué bù qiáng liú]
'Yao Zou Bian Zou Jue Bu Qiang Liu' means to leave without hesitation if necessary and not to hold on forcefully. It implies a kind of self-respect and determination: If a person or situation doesn't meet one's expectations anymore, don't stay or try hard to keep it.
