| In 719, as to exchanges of documents between Sogo (a monk of a managerial post)/Sango (three monastic positions with management roles at a temple) and Zokkan government officials, which should use cho, it was stipulated that a form of "I" (移) should be used by replacing Chinese characters "I" (移) with "cho" (牒). |
養老3年（719年）には、本来牒でやり取りが行われる僧綱・三綱と俗官官司との文書のやり取りは、「移」とあるべきところを「牒」と置き換えた上で移の書式で作成することとされた。 |
