The only thing that involves the so-called character is that the ladder is done like a defeat. Mozi thought there would be a war when he attacked the city with this weapon, so he stopped it. As for how to think and do like losing, there is no introduction. Later generations in the Han and Tang Dynasties, some unofficial history scribbled some so-called allusions, which were completely absurd and unreliable.
Mozi said: losing is like a ladder. The mountains are all over the world, and the so-called good attacking tools should also take Song, so Mozi stopped at a loss.
