There are several Tang Bohu in history. Please help explain the difference in detail.

According to research, there are three Tang Bohu in Chinese history. First, Tang Bohu, a scholar in the Northern Song Dynasty, was born in Dan Ling County, Sichuan Province. He specializes in the Book of Changes, Spring and Autumn Annals and other ancient books, but he is not famous because he has no masterpieces handed down from generation to generation. The second Tang Bohu was called Tang Yin, one of the "Four Great Talents in Jiangnan" in Ming Dynasty. The third Tang Bohu was also from the Ming Dynasty, a little later than Tang Yin. Although he is a Confucian scholar in Suzhou, he has made no achievements. Later, he married Qiu Xiang, the daughter of Hua Taishi. Because he and Tang Yin share the same surname, the same dynasty and the same origin, later novelists moved his "Lighting Chou-heung" to Tang Yin, and concentrated on shaping a "romantic genius Tang Jieyuan". In this way, Tang Bohu, who looks like Chou-heung, has been forgotten by the world.
