Zhang Liangji is not talking about specific strategies, but that he is very strategic.

It is said that Zhang Liang accidentally obtained "Tai Gong's Art of War" written by Jiang Taigong Lu Shang. Help Liu Bang ascend to the throne. After Zhang Liang received the Taigong's Art of War from the old man, he studied it day and night, pondered over and over again, and finally became proficient in the art of war, with unpredictable opportunities.

The wall-crossing ladder

The wall-crossing ladder is the dialogue between Gongshu Ban (Lu Ban) and Mozi during the Spring and Autumn Period of the Eastern Zhou Dynasty and the Warring States Period:

The Warring States Period , once, King Hui of Chu sent a public transportation team to make ladders (siege equipment, that is, ladders over the wall) in preparation for attacking the Song Dynasty.

Mozi knew about it and walked for ten days and nights. He came to see Gongshu Ban in Yingdu, Chu State, and said, "There is a man in the north who bullies me. Please help me kill him." Gongshu Ban didn't Happy. Mozi said: "I can give you a lot of gold." Gongshu Ban said: "I pursue benevolence and righteousness and do not kill people casually." Mozi said: "The land of Chu is vast and abundant, but the population is sparse and insufficient. Why should we use the insufficient population? Go and seize the remaining land? Song has not offended Chu, so why should Chu attack it? You uphold justice and do not kill the person who bullied me, but you help the king of Chu to attack the innocent Song. Isn't it just killing people casually?" Gongshu Ban said, "What you said makes sense, but I have already promised the King of Chu." Mozi asked Gongshu Ban to take him to see the King of Chu.

Mozi met the King of Chu and said: "There is a man who does not ride in his own good car, but steals his neighbor's shabby car; he does not wear his own silk, but steals his neighbor's coarse cloth; What kind of person is he who doesn't eat his own food but steals his neighbors' chaff? "The king of Chu said, "This man loves stealing." Mozi said, "The country of Chu has a radius of five thousand miles, and the country of Song has a radius of five thousand miles. Baili; the state of Chu is the richest in the world, and the state of Song has nothing. What is the difference between attacking the state of Song and that person who loves stealing?" King Chu said: "Although Gongshuban has built a ladder for me, I must Attack the Song Dynasty." So Mozi asked He Gongshu Ban to demonstrate the offensive and defensive formations on the spot, and the King of Chu agreed. Mozi took off his belt to build a city, and each used pieces of wood as tools to compete with the public transportation team. At the beginning, Mozi defended the city, and Gongshu Ban tried nine different methods of attack, but none succeeded; when it was Gongshu Ban's turn to defend the city, he failed for the third time. The Gongshu Ban put down the pieces of wood, and Mozi said: "I have sent three hundred disciples to help the Song Dynasty defend the city. Each of them knows my way of defending the city."

The King of Chu was silent for a while. After a while, he said: "I have decided not to attack the Song Dynasty."

Both Zhang Liangji and Guoqianglai are talking about resourcefulness

"You have Zhang Liangji, I have "Wall ladder." This sentence means: You have a powerful strategy, and I also have a countermeasure. Everyone has a countermeasure, and no one gives in. When the soldiers come, they will block it, and when the water comes, the soil will cover it up.
