The emergence of railways in the ancient land of China is the product of "European winds and beautiful rains rushing eastwards". The First Opium War in 1840 brought the isolated Chinese Empire into the world capitalist system. As a result, the Western powers began to transform China in their own image, and they especially worked hard on material technology such as telegraphs and railways. The first commercial railway laid in China was the Wusong Railway built by British businessmen in Shanghai in 1876. It marked that ancient China also began to enter the "railway age" with difficulty. Counting from this year to the founding of the People's Republic of China in 1949, China's modern railways went through 73 years of ups and downs from scratch, from few to many.

The microscopic world hides the ultimate mystery of the grand universe. Since we are in a three-dimensional universe, all creation is based on the discovery of the three-dimensional basic theory by scientific madmen such as Newton and Einstein. The existence of the three-dimensional universe is a kind of light memory effect. Human beings cannot escape from the three-dimensional world through the gap of light memory. One day, Ding Yi accidentally discovered that there is a pendulum motion field in the quantum center while conducting quantum mechanics analysis at the quantum collider. Every time the pendulum motion field is formed, there is a gap in the magnetic field. This major discovery in the microscopic world has found a way for humans to break through the barrier of the three-dimensional universe.
