What does this sentence mean, "the world is dazzled, and there is only one school of thought contending"?

"The whole world is dazzling, and only a hundred schools of thought contend." It means that Guiguzi is better than millions of famous teachers of all ages. It is also the role of one person to achieve a hundred schools of thought and block all countries' comments. It is about the wars fought by various countries during the Warring States Period. Zhang Yi, Su Qin, Pang Juan, Sun Bin and other outstanding figures stirred up the world and made history.

The sentence "I am the only one in the world, and a hundred schools of thought contend" comes from the bureau of Gui Guzi, which mainly tells the brilliant legend of Gui Guzi, the founder of the strategists, yin and yang, and Taoism.

During the Warring States Period, an old man (real name Wang Xu) lived in seclusion on a mountain called Guixi Guigu (now Hebi City, Henan Province). He studied, meditated in the mountains every day, lived an isolated life away from the world. However, for more than 2,000 years, strategists respected him as a saint, strategists respected him as an ancestor, fortune tellers respected him as an ancestor, and Taoism regarded him as the ancestor of Wang Chan.

Guiguzi only went down the mountain once in his life, and only received four apprentices, Pang Juan, Sun Bin, Su Qin and Zhang Yi-all of them were nobody before they entered the mountain, and all of them shined brilliantly and won eternal fame. These four men used the military strategy and vertical and horizontal arguments taught by Guiguzi to make a living in various countries, which influenced the political situation in the troubled times of the Warring States.

First, Pang Juan went down the mountain and made great efforts to help Wei stand out; Soon Sun Bin became the strategist of Qi, and Wei was totally embarassed. Then Su Qin, wearing the seals of the six countries, persuaded Qi Xin to work together to keep Qiang Qin from going out of Hangu Pass for fifteen years; In the end, Zhang Yi, that is, Qin Xiang, teased the governors of the world with his golden words, which made Su Qin fall short and opened the prelude to Qin Shihuang's unification of China.
