There are always people around who like to sow discord. What should I do?

How did you handle it before? Stay away from it, do more and talk less, and protect yourself is the first. If this is the usual pattern of TA, others will have their own cognition and judgment after a long time, and those who are clear will be clear. Of course, it depends on your relationship with TA, your situation and your concerns. If you feel that your interests have been harmed, you can directly "fight back." There is no choice, but there are many choices. No matter which choice you make, you can be mentally prepared to bear the consequences.
