媳妇天塌下来都有我扛着
[xí fù tiān tā xià lái dōu yŏu wŏ káng zhe]
'Wife, even if the sky falls, I will bear it' represents unwavering support towards one's wife, signifying that no matter what challenges life brings (even something extreme like “the sky falls down”), they would always be there supporting and protecting their beloved.
