Mozi is not a Taoist immortal, because the Mohists in the hundred schools attach importance to science and engineering, so he is still in the category of literature and history. Mohism, which is too down-to-earth and unable to be loyal to the public in thought, is a theory that the monarch cannot use. Secondly, none of the successors of Mohism can reach the level of Mo Zhai, and Mozi is the ultimate saint who is far superior to others. In ancient China, the monarch hoped to rely on the thoughts of sages to be loyal and forgiving to the masses, so as to achieve the effect of governing the country. Mohist ideas can not only be loyal to their own people, but also have military strength to resist a country, so they cannot be tolerated by monarchs. No monarch can accommodate educators, strategists and experts who threaten his rule. Let's analyze several important factors of Mohism's gradual demise.

First, Mo Zhai's work ability is too strong, and no one can inherit his personality charm, which is one of the reasons why Mohism slowly disappears.

Mo Zhai has extraordinary personality charm, and only his personality charm can condense the energy of Mohism. After death, no one can inherit his personality charm and condense Mohist energy. So Mohism collapsed and went to national subjugation.

Second, the strength of Mohism can resist a country, and the character of refusing to do it is one of the reasons why Mohism slowly disappears.

The core idea of Mohism is chivalry, and its strength can also affect a country's national defense personal behavior. Mo Zhai and Luban VII launched a simulated confrontation because of the siege and defense. Then, Mo Zhai completely defeated Luban VII. Mo Zhai defended a country, intercepted a war, but angered a monarch.

Third, Mohism is a scientific school, which is one of the reasons why Mohism slowly disappeared.

Mohism is a scientific and reasonable school, and it does not fool people ideologically. It gives the world a scientific and reasonable truth. The most famous scientific and reasonable core concepts in Mohism are pinhole imaging and gravitational acceleration. In addition, Mo Zhai has made great contributions in the fields of mechanics and mathematics. But at that time, this kind of scientific rationality was not what the monarch needed, but a threat.
