如淳, a government official of Wei dynasty (Three States Period), considered the custom of 'getting a tattoo on their faces (entrusting)' to be the origin of Wa, but Shinsan and Gan Shiko (Yan Shigu) denied the possibility because of such reasons such as the phonetic difference between 倭 and 委.
魏(三国)の官人、如淳は「人面に入れ墨する（委する）」習俗をもって倭の由来と論じたが、臣瓚や顔師古らから、倭と委の音が異なることなどを理由に否定されている。
