暮然回首发现身后几条狗
[mù rán huí shŏu fā xiàn shēn hòu jĭ tiáo gŏu]
The phrase humorously describes a situation where, after turning back, one unexpectedly finds trouble or annoying followers, possibly used to describe people who keep causing problems or are constantly nagging you. This saying comes from an ancient Chinese poem but the 'dogs' part has become a humorous adaptation.
