During the reign of Emperor Wen of the Western Han Dynasty, a general named Guan Fu, born in Yingyin County, earned great merit for crushing the rebellion of the Wu and Chu princes and was appointed as a palace attendant by the emperor. However, just a few months later, he broke the law, lost his official position, and ended up idling away his time in Chang'an.
Guan Fu was a man of fierce integrity, quick to anger and prone to drunken outbursts, yet he despised flattery. He would openly humiliate any noble or powerful figure he did not respect, but treated the poor and lowly with genuine equality, often praising talented juniors and humble scholars in public gatherings. For this, the literati held him in high esteem.
Of course, Guan Fu's greatest flaw was his heavy drinking and lack of learning, which ultimately led to his entire family being executed in Weicheng—a fate closely tied to these shortcomings.
Later, the idiom "a dense crowd of people" was often used to describe a very large number of people, or to refer to occasions with many people.
