How much of a gangster was Liu Bang, the great ancestor of the Han Dynasty?

Hello.

In the "Seven Sages of the Bamboo Grove", a literary idol group in the Wei and Jin Dynasties, a man named Ruan Ji once said a very famous saying: "There are no heroes, so Zhuzi became famous." The Shuzi here is probably Liu Bang. If you put it in vernacular, it would probably be "a person who was not very arrogant at the time actually made this old gangster famous." From then on, we identified Liu Bang's identity as not only "emperor", but also "rogue", or simply combined into one, called "rogue emperor".
