Lai Buyi and Bei Yunbing, are these characters real in history?

Formerly known as Fenggang Lai, Wen Jun, Buyizi, also known as Lai Buyi, also known as "Prophet Mountain Man", a native of Fengshangang, dingnan county, Jiangxi. Born in Song Huizong (A.D.11~1126), he was a nine-year-old high school scholar. He used to be a Buddhist, but he was framed by treacherous court official Qin Gui and lived in exile for a long time. Lai Buyi has traveled almost all over the motherland. With his superb geomantic theory and technology, he helped the poor and resisted the strong, leaving many myths and legends, and his reputation as a "geomantic master" spread like wildfire. Hongkong, Guangzhou, Yingde and other cities are all located near Lai Buyi. Legend has it that Wu Qing Xu was taken away by the white ape, the messenger of Nandi, as soon as it was drafted. More than one hundred years later, it was passed on to Liu Bowen, and Liu Bowen helped Zhu Yuanzhang to achieve imperial industry. It is said that the ancestral grave of Dr. Sun Yat-sen is also in Lai Buyi. Later, Lai Buyi, who saw through the world of mortals, lived in seclusion in the mountains and kept company with green hills and white clouds, but disappeared. Lai Buyi is regarded as one of the four founders of Kanyu in southern Jiangxi. Buyi Temple in Lai Buyi's hometown is listed as a key cultural relic protection unit and a tourist attraction, and Hong Kong compatriots come to pay their respects in an endless stream. Handed down from ancient times, there are "urging officials" and the like.
