Which dynasty did Lai Buyi belong to?

Fenggang Lai, whose original name is Wenjun, and his own name is Buyizi, is also known as Lai Buyi, also known as "Prophet Mountain Man", from Fengshangang, dingnan county, Jiangxi Province. Born in Song Huizong (111-1126 AD), he was a scholar in high school at the age of nine. Once a Buddhist, 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 exquisite geomantic theory and technology, he helped the poor and helped the weak and resisted the strong, leaving many mythical legends, and his reputation as a "master of geomantic omen" spread like wildfire. Hongkong, Guangzhou, Yingde and other cities are all located by Lai Buyi. Legend has it that Lai Buyi's preface to Qingwu was taken away by Bai Ape, the messenger of the Emperor of South China, just after it was drafted. After more than one hundred years, it was passed on to Liu Bowen, and Liu Bowen assisted Zhu Yuanzhang to achieve the imperial industry. It is also said that the ancestral grave of Dr. Sun Yat-sen was also located in Lai Buyi. Later, Lai Buyi, who saw through the world of mortals, hid himself in the mountains and forests, and kept company with the green hills and white clouds, but he disappeared. Lai Buyi is regarded as one of the four founders of Kanyu in southern Jiangxi. The 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 so on.
