Why is it said that new things must defeat old things in the process of development? If there is no destruction, there will be no establishment; if there is no destruction, there will be no establishment of the new. If the old things are not destroyed or defeated, how can new things be built up? This is also the general law of the development of things. New things appear in society. There will always be old things that need to be updated. Otherwise, the existence of old things will not allow the development of new things. So new things and old things are also a contradiction. Zinc food is derived from the development of society. According to people's concepts, new things can be produced only with the development of society. This is also the inevitable trend of the times. This is true of everything, every new thing that comes along. There is a process for people to accept it. It will occupy a certain market in society, otherwise people will not be able to accept new things. While accepting new things, I will gradually be canceled or not recognized by people. In this way, new things will inevitably defeat old things. The same is true for every change in society, the development of society. It is a process of defeating old things when new things appear. Otherwise, society cannot progress, society cannot develop, and people cannot change their thinking. At the same time, we should all get rid of old things. This is also a very difficult thing, and there are often some old things. Form a stereotype in people's minds. This kind of old TV will affect the stabilization and establishment of new things in the mind. At the same time, in the process of destroying old things, this new thing is gradually formed in the mind. Everyone grows and thrives in the struggle between old and new things. Only then can we have a re-examination and understanding of society. Everyone must break an old traditional concept at any time. There is no need to memorize old things and let them occupy the mind. People who can never make progress will never make progress. If they cannot make progress, society will not develop. Therefore, everyone should have a sense of new things. Re-understand the difference between new things and old things, otherwise we will stick to the old concepts of the past. Holding on to old things often makes people's thinking solidify. The solidification of ideas affects the development of new things in society. It also affects people's understanding of new social things. I think the understanding of new things is human. A development of thinking. Otherwise, we will always stick to the old ideas of the past and regard the development and progress of society.
