Legalists: The reform in Guanzhong during the Spring and Autumn Period and the rise of legalists in Qi made Qi the first overlord in the Spring and Autumn Period. In 356 BC, Shang Yang began to reform in the State of Qin and advocated governing the country according to law. About half a century later, Qin surpassed the six eastern countries in economy, military and politics. Due to the gradual decline of the six eastern countries, Qin was finally unified. However, the good times did not last long, and the cruel criminal law and tyranny of the Qin Empire also led to its demise. Great improvements have been made in the continuous revision of national laws in the next two thousand years, but until the modern history of China, cruel criminal laws still existed. For example, the top ten tortures in the Qing Dynasty.

Confucianism: As we all know, the founder was founded by Confucius, a great thinker and educator in China. Confucius' students can be said to be all over the world, but this school suffered a devastating blow after the reunification of Qin. However, this idea has been handed down, and in the Han Dynasty, the idea of "ousting a hundred schools of thought and respecting Confucianism alone" appeared.

During the Warring States Period, "a hundred schools of thought contend" was the first ideological emancipation movement in the history of China, and it was also the period of the disintegration of slave society in China. These schools and theories have left endless spiritual wealth to future generations. In the next two thousand years, many schools of thought are still staged in turn on the historical stage.
