我没有透彻所谓的人情世故
[wŏ méi yŏu tòu chè suŏ wèi de rén qíng shì gù]
Roughly translating to 'I don't have thorough knowledge of what we called human relations', the holder likely acknowledges their lack of savvy or worldly wisdom regarding the intricate dynamics involved in social interactions and relationship handling, perhaps indicating innocence or naivety or simply stating a refusal to comply with superficial social conventions
