The masterpiece "Twenty-Four Histories" records our country's social history of more than 4,000 years, which is all-encompassing and all-encompassing. It has both historical and literary value. It is a reference for politicians of all ages. It is a treasure trove of mirrors for military strategists and thinkers to learn from the past and the future, govern the country and ensure peace, cultivate oneself and manage the family, and conduct oneself in the world.

In addition, there are at least two important reasons why Mao Zedong studied "Twenty-Four Histories" diligently.

First, from the perspective of Mao Zedong’s ideological origins, he did not study abroad in his youth because he wanted to understand the essence of China’s ancient and modern doctrines and systems. At that time, many of his contemporaries went abroad to study, and his classmates also advised Mao Zedong to go abroad to hone his skills, but Mao Zedong ultimately stayed in China.

Secondly, he believed that the advantage of staying in China for exploration was that he could read the translation much faster than the original version, which would help him gain more knowledge in a shorter time. World civilization is divided into two streams: East and West. Eastern civilization accounts for half of world civilization. However, Eastern civilization can be said to be Chinese civilization. It seems that we should first study the outlines of our country's ancient and modern doctrines and systems, and then study abroad in the West to have something to compare with.

If we want to make a little contribution in today's world, of course we cannot escape from the territory of "China". Regarding the situation in this territory, it seems that on-the-spot investigation and research are indispensable. If this level of kung fu is done when you return from overseas, it may be a little difficult due to personnel and life issues. Might as well do it now.

He also said that I feel that I know too little about my own country. If I spend my time in my own country, it will be more beneficial to my country.

In order to learn from history, we seek inspiration, experience and lessons from history for governing the country. Studying and studying Chinese history includes studying the "Twenty-Four Histories" and understanding and grasping "the gist of ancient and modern doctrines and systems." The most important purpose is to serve today's real struggles. Learning from the past and knowing the future is for the purpose of governing the country and ensuring peace.

Learn to understand China’s thousands of years of cultural heritage, critically inherit and develop the essence of our nation’s cultural heritage, and learn from today’s and tomorrow’s political, social, economic, scientific, cultural and other construction and development Mao Zedong loved history and worked tirelessly to study and study the "Twenty-Four Histories".

These thoughts, opinions, and practices of Mao Zedong in his youth, especially his proposition that "it seems that we should first study the outlines of our country's ancient and modern doctrines and systems", are consistent with his later efforts to read "Twenty-Four" "History" are closely related.

The former is the cause and the latter is the effect. In his later years, Mao Zedong insisted on reading "Twenty-Four Histories" in order to better and more deeply understand the "gist of ancient and modern doctrines and systems" of China, and to know more about his own country. "Twenty-Four Histories" is the best and most complete knowledge collection for understanding the "gist of ancient and modern doctrines and systems" in our country.

To fully understand China's thousands of years of history, you must read "Twenty-Four Histories". As Mao Zedong said in 1975 when he had a conversation with Teacher Lu Di about reading the "Twenty-Four Histories", most of the "Twenty-Four Histories" are false, and most of the so-called factual records are also false. But if you don’t read it because most of it is fake, then that’s metaphysics.

If you don’t read, how can you understand history? On the contrary, if everything is believed to be true and every sentence in the book is regarded as a true creed, that is historical idealism. The correct attitude is to use Marxist standpoints, viewpoints and methods to analyze and criticize it, and turn upside down history.
