Words and deeds are all means of education. Teaching is teaching, teaching is teaching, teaching is teaching, teaching is teaching, teaching is teaching and teaching is teaching. Words and deeds are used by educators to summarize and illustrate the teaching content and educate the educated. Words and deeds mean that educators implement the content of words and deeds, especially that educators practice what they want to say and do, so as to educate the educated. The two complement each other, but they are slightly different.

Our education from primary school to university is all about example, not example. If teaching by example is more important than words, it can only be said that the education model all over the world is completely wrong.

There is an idiom: Why did the ancients put words and deeds before words and deeds, not before words and deeds?

Setting an example is limited by time, place, occasion and opportunity, which may be far from being achieved. Since it can't be achieved, what is its significance? Please don't run away from this possible situation.

Matters needing attention in the demonstration:

(1) Innovation. What's new and what's new can't be logically new, because seeking novelty should not only give the audience a bright feeling, but also make it easy for the audience to accept. The novelty of logic is not easy to accept in a short time.

(2) For the questions thrown by opponents, you can pass the buck, and there is no need to answer with an absolute answer.

(3) Any idea is useful to both sides, depending on how you use it.

(4) Seize each other's loopholes! You can't guess each other subjectively.

(5) learning by example. What examples should be given and how to give them are disgusting.

(6) Be fully prepared! Knowledge accumulation is a necessary condition to win the debate, but it is difficult to achieve ideal results without skills.
