自己挖的坑,跪著也要填完 [zì jǐ wā de kēng, guì zhe yě yào tián wán] Expression. Since the hole is digged by myself, I have to fill it even if that means kneeling on the ground throughout the process. This Internet slang term means that, once you make a decision or commitment, you have to pay the dues no matter what.
