我历史不好别和我谈曾经
[wŏ lì shĭ bù hăo bié hé wŏ tán céng jīng]
Translates to 'don’t bring up the past since I did badly at History'. Likely used humorously as some sort of excuse for avoiding discussions about historical events or reminiscing times gone by due to either real struggles in studying history or a metaphorical expression of escaping reality
