Wú Shāng 吳商 (third century, Sūn-Wú 孫吳 dynasty), Wú-court ritualist, dates not preserved. He has no standard biography in Sānguó zhì and is known principally through citation in Dù Yòu 杜佑’s Tōngdiǎn, where his Zálǐ yì 雜禮議 (KR1d0133) is preserved as a single-juàn fragment.
His principal documented position is on the yìxìng-wéi-hòu (different-surname adoption) problem: the spirits do not partake of non-clan offerings, so the adopted heir must continue mourning for his birth-kin. This is one of the earliest medieval Chinese ritualist objections to the widespread Three-Kingdoms practice of different-surname adoption.
