In China official documents in a form of i have been used since ancient times, and according to "Bunshinchoryu" (the oldest Chinese literature and rhetoric compendium) "I" (移) means "to change the real world,"because "I" (移) can be represented in a Chinese character which means "change" instead of one which means "move."
移は中国においては古くから存在した公文書の様式であり、『文心雕龍』には移が易に通じ、「俗を易える（変える）」の意味を有すると解している。
