In such a Hargan, was there such a person in ancient times?

There is no such person in history. Sue Chahar Chen is the hero in Su Qi, the champion of martial arts, and one of the classic comedy characters played by Stephen Chow. Romantic, martial arts, rich background but illiterate, can't even write a name. Because he cheated in the imperial examination, he was demoted as a beggar by the emperor. By chance, he learned peerless martial arts and became the leader of the Beggars' Sect.

Extended data:

Born in son of the general, Guangzhou, he was framed for being the top scholar in the State of Wu, and was punished as a beggar by the emperor. At this time, Tianjin Zhao Wuji entered the imperial court and persecuted beggars everywhere. It turns out that the four elders of the last generation of beggars' gangs killed the former leader of Tianjin, and the leader of beggars' gangs was also killed, so the method of beating dogs with sticks was lost. Besides, the Beggars' Sect is divided and leaderless. The elders of the Beggars' Sect chose Su Can as their successor, and they preached Sleeping Arhat Boxing.

He succeeded in learning art and became the new king, uniting the members of the national beggars' sect to strive for self-improvement and struggle against Shinrikyo. Zhao Wuji wanted to pre-empt the Emperor and support himself, but the news leaked to Su Can. When the Emperor was hunting, Shinrikyo challenged him. Fortunately, Su Can arrived in time and saved the emperor. The emperor wanted to restore Su Can to his official position. Su Can used to be a beggar, but he was too lazy to be an official. He just wants the emperor to rule the country. Finally, the emperor did not think of it. He gave Su Can a beggar's bowl and wrote "Begging according to the order" at the bottom.
