It means: If you unite many soldiers, you will definitely win as long as you fight, and you will definitely win as long as you attack the city. I am not as good as Han Xin.

This sentence comes from "Han Gaozu's Discussion of the Three Heroes" in "Historical Records: The Benji of Emperor Gaozu". The original text is as follows:

The emperor established wine in Luoyang Nangong. He said: "The princes and generals do not dare to hide from me. They all express their feelings. What is the reason why I have the world? What is the reason why the Xiang family has lost the world?" Gao Qi and Wang Ling said to each other, "Your Majesty sent people to attack the city and seize the territory. Because of this, the world has the same benefits; Xiang Yu is not the same, those who have merit will harm him, and the wise will doubt him, so he will lose the world. In addition, I am not as good as Zifang (Zhang Liang, also known as Zifang); in controlling the country, pacifying the people, providing wages to the army, and never cutting off the food supply, I am not as good as Xiao He; even with millions of people, I will win the battle, and attack I must take it, I am not as good as Han Xin. All three are outstanding, and I can use them. This is why I take over the world. Xiang Yu has one more example and does not use it. This is why he is favored by me." The officials persuaded him. Translation

Liu Bang, the emperor of the Han Dynasty, held a banquet in the Nangong Palace of Luoyang and said: "Princes and generals, please don't hide from me and tell the truth. What is the reason why I won the world? What is the reason why Xiang Yu lost the world?" What?" Gao Qi and Wang Ling replied: "Your Majesty asked people to capture the city and obtain the land, and then gave it (town, land) to them, which is the same as the interests of the world. However, Xiang Yu is not like this. He kills people with meritorious service and doubts. This is the reason why talented people lose the world." Liu Bang said: "You only know one aspect, but you don't know the other aspect. I am not as good as Zhang in making plans in the big tent and deciding the outcome thousands of miles away. Liang; to pacify the country, pacify the people, provide military pay, and constantly cut off the road to transport food, I am not as good as Xiao He; to unite many soldiers, as long as the battle is successful, as long as the siege is successful, I am not as good as Han Xin. , I can appoint them, this is the reason why I conquer the world. Xiang Yu has Fan Zeng but does not appoint (him), this is the reason why he is captured by me. "All the ministers were sincerely convinced. Creation background

On the third day of February in 202 BC, Liu Bang proclaimed himself emperor in Dingtao, which was known as the Western Han Dynasty or the Former Han Dynasty in history. In the month when Liu Bang proclaimed himself emperor, he came to Luoyang from Dingtao to comment on his merits. The civil servants and generals were all very happy, so he made Luoyang the capital (note: one month later, Yueyang was officially made the capital Chang'an soon). This incident happened at this time.
