When the Army Approaches Hangu Pass, Pei Gong Cannot Be Let Go.

Once he woke up from his dream, he traveled back to two thousand years ago, during the chaotic times of the late Qin Dynasty, and became the overlord of Western Chu after the victory in the Battle of Julu. The reputation is already world-famous; the military strength is 600,000, and the world's soldiers and horses are under control. Victory was already beckoning to him, and he rushed straight to Hangu Pass, waiting for Liu Bang to retreat and destroy him in one fell swoop. But when I came to Guanqian, why was it different from what he thought? Shouldn't Liu Bang send people to close the gate? How can I go out of customs in person to greet him? Is this right?
