I remember a wonderful example in the original debate, that is, the story of Cinderella. The one who emphasized the importance of external beauty quoted Cinderella as saying that if she hadn't been turned into a carriage by pumpkins, beautiful clothes and crystal shoes won by birds, she wouldn't have been loved by the prince. The other party retorted that this example just shows the importance of inner beauty, because Cinderella is kind-hearted, otherwise how could Cinderella's two beautifully dressed sisters not be favored by the prince? Then the party who emphasized the importance of external beauty immediately took over: how did the prince finally confirm that Cinderella was the one he was looking for? That's because Cinderella's feet just fit into the glass slipper. Is Cinderella's feet of moderate size inner beauty rather than outer beauty? ! ! At that time, the anger on the field was super warm. Although it is not logical to think about it carefully, it is still very effective to encourage anger and win popularity on the spot.
I'm verbose, and I don't know if I can help.
This debate should be rich in materials. Of course, in addition to the materials you are looking for to prove your point of view, you should also consider what common examples the other party will prepare, and then you should prepare rebuttal arguments, because China people have traditionally pursued the importance of inner beauty. Only in this way can we defend at the same time when attacking each other, and achieve both offensive and defensive.
Oh, I used to be on the school debate team. Come on!
