The world is like a chessboard, and a person is like a pawn. Only after crossing the "Chu River and Han Dynasty" can he rampage and realize his own life value. Everyone is bound and restricted by an invisible boundary. Some people dare not break through the boundary, just live and work in the boundary in a proper way, and in the end they are just mediocre and mediocre. However, some people dare to break through the boundaries and get rid of the shackles of those red tape, so they also enjoy the different scenery outside the boundary, appreciate the different wonderful things outside the boundary and live an extraordinary wonderful life. I admire the man who invented the Guinness Book of Records. He encouraged people to break records, he encouraged people to go beyond the boundaries of thinking, and he knew the fun and excitement after breaking the boundaries. With Guinness, there will be a constant breakthrough in physical and ideological boundaries. Bubka, a famous pole athlete, famously said, "Records are for breaking." How arrogant and exciting! He kept breaking his own record and breaking the boundaries of sports in people's minds. Because he was intoxicated with breaking through the boundaries of human physical strength, he didn't feel lonely at the top, and he forgot the physical fatigue and pain, so he created one incredible record after another and broke through the recognized boundaries of physical strength. In the process of challenging and breaking through the shackles of the world, he naturally has extraordinary pole achievements and has a super high level that others can't match. People can never make progress if they can't get rid of the shackles of thought. In the era when geocentric theory was universally respected, a group of geniuses broke through the ideological boundary and put forward Heliocentrism, making outstanding contributions to the development of astronomy. In the closed-door and arrogant late Qing Dynasty, there were such a group of young people who broke through conservative ideas and started to learn advanced technology from the West, which laid the foundation for the development of China's industry. After discovering the phenomenon of "photoelectric effect", physicists struggled to explain this phenomenon, but the genius Einstein broke through the boundary of the general thinking trend and put forward the wave-particle duality of light. In the past, people were good at drawing conclusions by analogy, but this property of light has no analogy in nature. Therefore, only by breaking through the boundaries of thinking can we explain this "magic" phenomenon. Without Einstein's idea of breaking through the "prescribed" boundary, this property of light would still be a mystery, not to mention the further development of optics. Only by breaking through the shackles of all kinds of boundaries can we appreciate the vicissitudes of life. "Boundary" is used to break through!
