你最好别把我的性格和态度
[nĭ zuì hăo bié bă wŏ de xìng gé hé tài dù]
This seems incomplete, but if expanded to a common expression like 'You Better Not Confuse My Kindness with Weakness,' the implication could be 'Don’t Mix My Character with My Attitude,' which means don't mistake my true nature based on how I behave on the outside.
