人生太多不如意何必要跟狗
[rén shēng tài duō bù rú yì hé bì yào gēn gŏu]
The phrase reflects a pessimistic outlook on life, indicating that there are too many disappointments in life; it questions why one would choose to live such a hard or undignified life (idiomatically comparing life with being like a dog). This can sometimes be self-deprecating humor.
