It is very important to know your mistakes and improve them

"Knowing your mistakes and being able to correct them" is the unique charm of sages throughout the ages. Many people can recognize their mistakes, but there are so few sages. This is because they know their mistakes and do not correct them, and they only take a small step on the long road of becoming a sage. It can be seen that it is particularly difficult and important to know and correct mistakes. In "Autumn Waters", He Bo "heard the Tao and thought that there was no one like him", he was happy and thought that all the beauty of the world was within himself.

But when he saw the vast and boundless North Sea, he realized how insignificant he was. It was this spirit of knowing his mistakes and being able to correct them that prevented him from being laughed at by the generous family. As a result, He Bo became a generation of saints and sages, admired by the world.
