In conjunction with the next lecture (“The World Pattern in the Sino-US “War”) to discuss the hostility between the United States and China, Trump must Make trouble for China, deny what China is doing, and shoot yourself in the foot.

An abnormal leader, he will deny the severity of the disaster.

Organized and manageable countries, such as Germany, quickly entered a state of epidemic prevention, mastering how to treat and how to prevent the spread of disease.

In contrast, Britain, Spain, and France are far behind. The internal epidemic in Russia is unknown. North Korea has strict controls and does not know the internal situation. Taiwan suffered heavy losses after the SARS battle, but it also made it possible to control the epidemic in time, and immediately mobilized medical personnel and medical units throughout Taiwan to do this.

Through these comparisons, we can see that management methods, management scale, and management experience have a great impact on the prevention and control of large-scale disasters in a country.

Second, one must be forgiving in the judgment of history

Yu Xinzhong: Professor of School of History, Nankai University, Expert in Medical Social History

Yu Xinzhong: Throughout the history of human plague, severe epidemics have had very different consequences for different regions and nations.

For example, the European Black Death caused a structural blow to the European population, while also contributing to the rise of science and rationality; while the smallpox in the Americas took away nearly one-third of the Native American population, it also caused The final decline of Indian civilization.

In China, on the one hand, the plague’s damage is much smaller, and on the other hand, it does not seem to have a tendency to influence Chinese history.

How do you think this difference is caused?

Xu Zhuoyun: If we choose two extremes: Europe and China for comparison, there are differences, but there are many intermediate types.

The Middle East, India, and later the Atlantic and Indian Ocean regions were all customers and vendors who passed by long distances, especially the large tribes who passed by marching into battle, causing rapid and large-scale proliferation.

With the globalization of the economy, the gap between culture and culture is indeed gradually decreasing.

A world that is changing, no authority exists. The church and the dominator you just mentioned, none of the dominators are willing to give up the right to dominate. But today the information is so widespread and the economic power is so powerful, no ruler can say “My dominant power is always in my hands.” Because the human brain is alive.

The human brain is alive, but at the same time it is dead. Everyone receives different information, different opinions, and different levels of digestion. How to integrate differences and disagreements to find more common ideals? This is a question worth thinking about. We all know that ideals are hard to find.

In the past, we called space fields and people. The first space is a point, the second space is a line, and the third space is a three-dimensionality.

If there is no topological structure, the gene structure diagram cannot be drawn; if there is no complicated spatial idea, there is no way to deal with the arrangement of multi-dimensional space and N-order space.

How to understand the universe? How do space and space fold, shrink, and twist? When different spaces collide, they are distorted and entangled to the point that there is no way to solve them with simple geometry. You must think about them from the perspective of diverse and changing spaces. The complexity of the diverse changing space can be traced to infinity.

The more knowledge we have, the more humble we should be. Most people, including Trump, don’t think so. Today, there is respect for knowledge, but we understand that knowledge is limited.

Most of the knowledge is constantly changing, and the most is the change of historical knowledge. Every time I reflect on yesterday, the meaning is different.

5. The Yangtze River is important and special

Culinary Kitchen: Founder and President of Takayama University

Wen Chu: You wrote in “Eternal Rivers”, “The Yellow River is yellow, it is hard; the Yangtze River is green, it is happy”.

I recently did something called “Ask the Yangtze River” for public welfare. Now the country also proposes that “green water and green mountains are golden
