这么努力只是不想被狗看轻
[zhè me nŭ lì zhĭ shì bù xiăng bèi gŏu kàn qīng]
Conveying intense dedication and effort put into something merely not to be underestimated or looked down upon. The mention of 'dogs' metaphorically signifies adversaries or critics who could undervalue one's worth or accomplishments without striving hard.
