The public transport board built a ladder for Chu, which will be used to attack Song. When Mozi heard this, he got up from Qi and walked for ten days and ten nights to get to the capital of Chu, Ying, to meet with the loser. The loser said, "What will you tell me?" Mozi said, "There is a man who bullied me in the north, and he is willing to kill him with your help." The public loss is not happy. Mozi said, "I am willing to give you ten pieces of gold." The loser said, "I am righteous and will never kill anyone." Mozi stood up, bowed to the loser again and said, "Please tell me about this. I heard in the north that you built a ladder and will use it to attack the state of Song. What is the crime of Song State? Chu has surplus land, but the population is insufficient. It cannot be considered wisdom to sacrifice insufficient population and plunder surplus land now. It can't be said that Song attacked it without sin. Knowing this and not arguing can't be called loyalty. It is not strong to argue without results. You don't kill one person, but you kill many people. You can't be said to be a wise man. " The loser convinced him. Mozi asked him again, "Then, why not cancel the attack on Song State?" The public loser said, "No.. I have already told the king of Chu. " Mozi said, "Why don't you introduce me to the King of Chu?" The public loser said, "OK."

when Mozi met the king of Chu, he said, "Now there is a man here who abandoned his gorgeous car, and his neighbor has a broken car, but he intends to steal it; Abandoning his gorgeous silk, the neighbor has a coarse blouse, but he intends to steal it; Abandoning his delicious food, the neighbor only has dross, but he intends to steal it. What kind of person is this? " The king of Chu replied, "This man must be suffering from theft." Mozi said: "The place of Chu is five thousand Li in Fiona Fang; Fiona Fang, the place of Song Kingdom, is 5 Li, which is just like a float compared with a broken car. Chu has a vast expanse of clouds, full of rhinoceros, deer and elk. The fish, turtles, catfish and catfish in the Yangtze River and Hanshui River are the richest in the world. In Song Dynasty, there were not even pheasants, rabbits and foxes, which was just like comparing delicious food with dross. Chu has precious wood such as giant pine, catalpa, Phoebe bournei and camphor. Song doesn't even have a big tree. It's like comparing gorgeous silk with coarse cloth and short coat. From these three aspects, I think that Chu attacked Song, which is the same type as people with theft. I think your majesty, if you do this, you will certainly hurt your morality, but you can't rely on Song State. " The king of Chu said, "Good! Even so, the public losing plate has built a ladder for me, and I must capture Song State. "

so I called the public loser to meet again. Mozi took off his belt and surrounded it like a city, using small pieces of wood as garrison equipment. Nine times, the public transport plate was equipped with ingenious and changeable equipment for siege, and Mozi resisted his attack nine times. The equipment used in the attack and battle of the public losing plate was exhausted, and Mozi's defensive tactics were still left. The loser was frustrated, but said, "I know what to do with you, but I won't say." Mozi said, "I know what you can do to me, but I won't say." When the king of Chu asked why, Mozi replied, "The meaning of losing the game is just to kill me. Kill me, and no one in Song can defend, so you can attack. However, 3 people, including my disciple, Bird Slippery Li, have been waiting for the invading army of Chu in the capital of Song State with my defensive equipment. Even if you kill me, the defenders can't kill me. " The king of Chu said, "Good! I won't attack the state of Song. "

this can be said to be a prominent example of retreating the enemy with your breath in history.
