Mozi left alone 10 day 10 night to see the king of Chu and Lu Ban, which stopped their attempt to attack the Song State. This righteous act will be remembered forever. The ideas of "fraternity" and "no attack" stand against tyranny and war from the standpoint of civilians. As long as he hears that a vassal is going to launch an unjust war to invade a weak country, he will immediately lead his disciples to stop it and help the weak country defend the city day and night; The Mohist swordsmen's regiment, "jumping from soup to blade without hesitation", assassinated corrupt officials all over the world, making officials have to worry about when they will lose their heads inexplicably; At that time, Mohism was a famous school in the world, known as "non-Confucian Jimo". Mozi, as the first tycoon of Mohism and a doctor in the Song Dynasty, has a very prominent position, but Mozi himself "wears brown clothes, takes clothes, works day and night, and takes self-suffering as the extreme" and leads a miserable life. These are all "chivalrous people, for the country and the people." Although Mozi is more of a thinker who takes the world as his responsibility, his behavior embodies the highest realm of chivalry everywhere.
