When was Beggar's Sect founded in martial arts novels?

In wuxia novels, Beggar's Sect was a long-standing and large-scale gang. Its founder could be traced back to the Ming Dynasty. According to legend, the founder of Beggar's Sect was Liu Baorui. He founded the sect at the end of the Ming Dynasty. At first, he only survived in the Jianghu as a dog fighter. Later, he gradually developed into a sect with a certain amount of power. Although Beggar's Sect's history was supported by legends and stories, there was no clear record of the exact time. However, martial arts novels by Jin Yong and others often depicted the history and characters of Beggar's Sect in the Ming Dynasty and Qing Dynasty to show the status and influence of the sect in the martial arts world.
