Be good at grasping each other's key points

In the debate, we should be good at grasping the other party's key points and refuting them tit for tat. The first is to refute the wrong argument and directly prove the falsehood and absurdity of the other party's argument by analyzing the facts; the second is to refute the argument and directly expose the hypocrisy of the argument, so the incorrect argument will be exposed; the third is to refute the argument by exposing the wrong logical relationship between the other party's argument and the argument.
