真心交友不交狗
[zhēn xīn jiāo yŏu bù jiāo gŏu]
Make real friends instead of dealing with dogs. Here, the word 'dog' refers negatively to disingenuous or dishonest acquaintances or connections who are merely seeking something from the individual rather than engaging genuinely. This suggests sincerity and openness in choosing friends and building relationships while distancing oneself from toxic or insincere people.
