In recent decades, the country's scientific and technological progress has mainly relied on two groups of people, one group of whom studied in the United States, Germany, Japan, the Soviet Union, Britain, and France, and went out in the early twentieth century. Of course, among these people, there are more people studying in Japan and studying military affairs; those who study in the Soviet Union are more engaged in politics; more people are studying literature in Britain; while those who study in the United States and Western Europe are more likely to study science and technology, physics, chemistry, and machinery, and they have played a great role in building atomic bombs and hydrogen bombs.

The second batch is mainly the generation selected through the college entrance examination after the resumption of the college entrance examination, and this part of the people later obtained advanced modern science and technology by studying in the United States, Japan, Western Europe and other countries, and then returned to China to teach new technologies, which greatly improved the country's scientific and technological level and narrowed the gap with Western countries.

The two groups of people are composed of talents selected through the college entrance examination, and it has to be said that the college entrance examination can still select outstanding talents, so the significance of resuming the college entrance examination that year is still extraordinary. Otherwise, if you can still recommend college by handing in white rolls like Zhang Tiesheng, you may not be able to build atomic bombs and hydrogen bombs in the end!

In the future, the development and progress of the country is still inseparable from high technology, or it needs talents. From ancient times to the present, the selection of talents in the mainland is carried out through examinations, practice has proved that this method is still reliable, and through the performance of recommending college, resulting in a certain stage of scientific and technological progress in situ. I hope that white-scroll students like Zhang Tiesheng will not appear again in the future.
