It is necessary to combine cold articles with social problems, guide scientific research with practical problems, and strive to solve the problems encountered by the people and the country. For example, Yuan Lao solved the problem of people eating, soil scientists solved the problem of poor soil cultivation, and experts in the field of environmental restoration solved the problem of environmental pollution.

These researchers also publish papers, many of which are high-quality foreign journals. At the same time, the benefit we get from these papers is to solve the practical problem, that is, to write the papers on the land of the motherland.

Besides, isn't that a scientific problem-oriented paper written on earth? Things involving the universe seem meaningless to the average person's life span. No, these pure scientific research may not be important to the life span of an individual, but it is very important to the development of the whole country and even mankind.

We can find laws and make good use of them, but rarely ask why, which makes us worse than others in the past scientific field. But not now, more and more people realize the importance of asking why, and we stand higher and higher in science.

And writing papers to understand why, people who contribute to the scientific cause of the motherland are also people who write papers on the land of the motherland.
