《资治通鉴·唐纪·唐纪八十一》
刘仁恭这才命令胜任持拿兵器的人全部出行，在他们的脸上刺字 字霸都 ，读书人就在他们的手腕或者胳膊上刺字 一心事主 ，于是境内的士人百姓，除婴儿小孩以外没有不刺字的人。
乃命胜执兵者尽行，文其面曰 定霸都 ，士人则文其腕或臂曰 一心事主 ，于是境内士民，稚孺之外无不文者。
Only then did Liu Rengong order all those able to wield weapons to depart, tattooing their faces with the word 霸 (tyrant). Scholars had the words 一心事主 tattooed on their wrists or arms. It turned out that other than infants, there was not a single person in the region, regardless of their social class, who was not tattooed.
