Xiao Tong
Over the years, Emperor Wu had increasingly given additional authorities to Xiao Tong the Crown Prince, and the relationship between father and son was dear. However, in 526, after the death of Xiao Tong's mother Consort Ding Lingguang (丁令光), the relationship would deteriorate. Xiao Tong sought out an appropriate place to bury Consort Ding, but while he was doing so, a land owner bribed the eunuch Yu Sanfu (俞三副) into convincing Emperor Wu that that piece of land would bring good fortune for the emperor, and so Emperor Wu bought the land and buried Consort Ding there. However, once Consort Ding was buried, a Taoist monk informed Xiao Tong that he believed that the land would bring ill fortune for Consort Ding's oldest son—Xiao Tong. Xiao Tong therefore allowed the monk to bury a few items intended to dissolve the ill fortune, such as wax ducks, at the position reserved for the oldest son. Later on, when one of Xiao Tong's attendants, Bao Miaozhi (鮑邈之), was squeezed out of Xiao Tong's inner circles by another attendant, Wei Ya (魏雅), he, in resentment, reported to Emperor Wu that Wei had carried out sorcery on Xiao Tong's behalf. When Emperor Wu investigated, waxed ducks were found, and Emperor Wu became surprised and angry, and wanted to investigate further. He only stopped the investigation when he was advised to do so by the prime minister Xu Mian, executing only the Taoist monk who had suggested the burial of wax ducks. Xiao Tong became humiliated in the affair, and was never able to clear himself completely in his father's eyes.
