链子再好也栓不住想跑的狗
[liàn zi zài hăo yĕ shuān bù zhù xiăng păo de gŏu]
This internet nickname implies a strong message about personal freedom and choices. The saying conveys the idea that even if someone is restricted, like with a 'chain', it won't stop them from making a decision to leave if their heart is determined to go elsewhere. It speaks of rebellion and individual choice.
