What is the purpose of Feng Menglong's creation of a think tank?

Feng Menglong once expounded his creative motivation in "A Tale of Think Tank": "People have wisdom, but there is still water; The earth without water is scorched earth, and people without wisdom are walking dead. Wisdom is used by people, and there is still water flowing on the ground. The terrain is full of water, and the personnel depression is full of wisdom. The forest of success or failure in Zhou Lan in ancient and modern times is not the result. " It can be seen that he wants to sum up the reasons of "success or failure in ancient and modern times" through humorous stories in the book, so as to inspire future generations and have far-reaching influence. Most of the stories in Think Tank are authentic, well-founded and vivid, which provides valuable information for us to study history today.
