Grasp the key points: You need to grasp the key points of the other party's point of view and refute them forcefully. 3. Use logic: You need to use logical reasoning to prove your point of view so that the audience can better understand your point of view. 4. Good at communication: You need to be good at communication and effectively communicate with the audience so that the audience can better understand your point of view. 5. Maintain confidence: You need to maintain confidence in your argument and believe that your point of view is correct and that you can convince the other party to accept your point of view.
