The romance of the Three Kingdoms is one of the four famous works in China. It reflects the magnificent history of the late Eastern Han Dynasty, from the struggle for hegemony to the confrontation of the Three Kingdoms of Wei, Shu and Wu, and then to the unification of the world. The romance of the Three Kingdoms contains many ingenious strategies, profound wisdom and superb management, which have a great impact on all walks of life. Some people read the romance of the Three Kingdoms and became famous politicians. Some people read the romance of the Three Kingdoms and became famous militarists. Some people read the romance of the Three Kingdoms and became famous entrepreneurs.

Scientific research needs tackling key problems. Scientific research is a war without smoke of gunpowder, which reflects a country's comprehensive economic strength, educational level and management ability. As scientific researchers, I think the romance of the Three Kingdoms should also have some inspiration for us. The most wonderful part of the romance of the Three Kingdoms is the battle of Guandu, Chibi and Yiling. Coincidentally, the three major battles were all won by the weak. Those who were several times stronger than the other side were defeated.

Once or twice is accidental, and three times in a row is inevitable. I think this reflects the level of science and technology at that time. Without advanced means of communication, too many soldiers could not command effectively. In particular, a person's time and energy to deal with things is limited, and the team is too large for the military commander to deal with and coordinate effectively. When the troops are too large, it is not only easy to belittle the enemy in battle, but also easy to shift responsibility to other troops without making every effort; when they retreat, they run very fast. Cao Cao, who ridiculed Yuan Shao, became Yuan Shao of Guandu in Chibi; Liu Bei, who ridiculed Cao Cao, became Cao Cao of Chibi in Yiling.

In the process of leading postgraduates, professors sometimes have similar phenomena: famous professors lead more and more postgraduates, and their teams become bigger and bigger. Sometimes, the quantity and quality of their achievements are not as good as the few students they brought when they were young. The young doctor who just graduated is equivalent to Cao Cao who started his own business. Although there are few graduate students under him, they all work together in the laboratory and produce good and fast scientific research results. When he was a professor and put on his hat, he unconsciously became a well-equipped Yuan Shao. More and more postgraduates were attracted to him, and he was on business for a lot of time. He really didn't have the energy to manage a large number of postgraduates, resulting in few research achievements and low quality.

It is not only a paradox, but also a certain rationality that the more graduate students they have, the worse their achievements will be. Only in this way can the young doctors who have just graduated be more energetic, and the scientific research team be able to push the waves behind the Yangtze River, and each generation is stronger than the other. However, today is different from the era of the Three Kingdoms. Advanced means of communication and scientific means of management can avoid this paradox. For example, in the large graduate team, the establishment of several capable scientific research groups, doctoral students to help with master's degree students, senior graduate students to help with junior graduate students, can effectively improve the effectiveness of scientific research. Therefore, with scientific and effective management and effective communication, large scientific research teams can produce more and better results, and there are many successful examples.
