What is the secret of Liu Bang taking the lead in realizing "entering the customs first is king"?

Liu bang entered the customs for the first time for two reasons: the first is objectivity, and he must thank the leaders for their appreciation and colleagues for their support. If it weren't for the strong combination of the two, Liu Bang might not get what he wanted. The second reason is subjective. Liu bang's own political consciousness is high and his skills are superb. He pretended to lure the enemy deep, but in fact he seized Xianyang by force. It was Liu Bang who took the lead in entering the customs and realized his dream by making the best use of the favorable weather, geographical location and human harmony.

Suddenly reported Xiang Liang defeat suicide, Wang Zhao stag besieged. Chu Huaiwang quickly made a military decision: one sent Xiang Yu to save Zhao, and the other sent Liu Bang to explore Xianyang. Why not send Xiang Yu to the west? Because Xiang Yu had the experience of massacre, he was directly ruled out. In Chu Huaiwang's view, since you want to go to Xianyang, you can't let Xiang Yu, a notorious person, go to Xianyang. Otherwise, we will also leave a cruel reputation for Xianyang people. How can we appease them?

That is to say, in addition to Chu Huaiwang's appreciation, Xiang Yu also helped Liu Bang with his "bad reputation". Then Liu Bang went all the way to the west, but he didn't use force to suppress Qin Jun's territory along the way, but used intelligence. Liu Bang kept conferring titles and honours along the way. On the basis of preserving their own strength, they also publicize their reputation of benevolence and righteousness. This plan was very beneficial to Liu Bang's later capture of Xianyang. After all, after the Qin Dynasty, everyone hoped to welcome a kind monarch or general.

So, after Liu arrived at his destination, he accepted Zhao Gao's request for peace talks for a pretence, and at the same time, he took advantage of his vigilance and seized Wuguan. It was the external force and my unremitting efforts that made Liu Bang realize the plan of entering the customs first.
