Why is Guiguzi's book banned?

Because the rulers banned this book because they were afraid that people would be in chaos when they learned the contents.

As we all know, Guiguzi's two most proud disciples are Su Qin and Yi Cheung. These two men also had the greatest influence on the situation during the Warring States period, which can be said to have caused chaos in the world. Although it doesn't matter whether there are such people in troubled times, it is a terrible thing if such people are in peacetime. Therefore, in the ancient feudal society, this book was banned by the rulers, and people were not allowed to read it.

Legend of Guiguzi's life story:

According to legend, a long time ago, there was a family named Zhao and a family named Zhou. They are neighbors. Zhao is a businessman, and Zhou is a farmer. The two families are closely related. Later, Zhao's business went bankrupt, and the Zhou family generously helped. In order to express sincere gratitude, Zhao promised to betroth his daughter to the Zhou family. Soon after, Zhou's parents died one after another, and his family's fortune fell. As a businessman, the Zhao family broke the marriage and contract.

Zhou's son missed his childhood, resented lovesickness and died. Zhao's daughter is a smart and virtuous woman. When she heard the bad news, she rushed to the grave of Zhou's son. She wailed, but she cried her eyes out because of excessive sadness. In a trance, it seems that Zhou's son wants her to take a grain of rice home from the grave.

When Zhao's daughter woke up, she found that there was indeed a rice plant around her. She really took it back to eat. Later, Zhao's daughter became pregnant, gave birth to a boy, grew up healthily and became a smart man. This is a generation of genius guiguzi who is revered as a god by later generations.
