Criticize and refute the enemy's theory first, and then show your point of view on this basis, that is, break first and then stand. As the saying goes: "If you don't break, you will stand, and if you don't break, you will flow." "Breaking" and "establishing" are inevitable links in argument. Only when "breaking" and "standing" are appropriate can we have a clear view and stand. For example, Lu Xun's "takenism" is typical of the method of breaking first and then standing. Firstly, the article reveals the essence and serious consequences of criticizing "sending away"; Then it expounds the basic viewpoint of "takenism" and criticizes the wrong tendency in dealing with cultural heritage issues; Finally, it summarizes the full text and points out the courage and quality that people who practice "takenism" should have, as well as the important significance of "takenism" in creating new national culture. Why did the first half of the article write "closed door" and "farewell"? This is because the author wants to establish "takenism", which is aimed at the problems existing in history and reality, so he must first "break", "close" and "send". The modern "closed door" will inevitably lead to the present "farewell". "Farewell" is an endless traitorous act, which will inevitably lead to the weakness and passive beating of the country. In the long run, it will inevitably lead to the extinction of the country. Therefore, it is urgent to adopt the "take-away doctrine" which is tit for tat with the "send-away doctrine". "Sending away" and "taking away" are two sides of the same question, and "breaking" is only for "standing", "breaking" is thorough and "standing" is firm.
