黃初中,為太樂令、協律都尉。漢鑄鐘工柴玉巧有意思,形器之中,多所造作,亦為時貴人見知。夔令玉鑄銅鐘,其聲均清濁多不如法,數毀改作。玉甚厭之,謂夔清濁任意,頗拒捍夔。夔、玉更相白於太祖,太祖取所鑄鐘,雜錯更試,然知夔為精而玉之妄也,於是罪玉及諸子,皆為養馬士。文帝愛待玉,又嘗令夔與(左原)〔左𩥄〕等於賓客之中吹笙鼓琴,夔有難色,由是帝意不悅。後因他事系夔,使(原)等就學,夔自謂所習者雅,仕宦有本,意猶不滿,遂黜免以卒。

Chai Yu was a bell caster of the Han dynasty who later cast bells at the Cao Wei court. He does not appear in the Romance of the Three Kingdoms.
Deeds
During the Huangchu era, Chai Yu served as Director of Grand Music and Assistant Commandant for Musical Standards. Du Kui ordered him to cast bronze bells, but their tones did not meet the prescribed standards, so they were repeatedly destroyed and recast. Chai Yu and Du Kui argued and together appealed to Taizu. After testing the bells, Taizu judged that Du Kui was skilled in the craft and that Chai Yu’s work was unsatisfactory, and sentenced Chai Yu and his sons to serve as horse keepers. (As recorded in the histories)
