There was an anecdote: during his stay in Tang, Kukai was ordered by the Emperor to rewrite Xizhi WANG's writing on the wall in the Tang Imperial Palace; Kukai wrote five lines at the same time by holding five brushes, one in each hand, in each foot, and in his mouth; people there were amazed and called him Gohitsu Osho.
