Mi Fu was among those for whom writing or calligraphy was intimately connected with the composing of poetry or sketching. It required an alertness of mind and spirit, which he thought was best achieved through the enjoyment of wine. Through this he reached a state of excitement rather than drunkenness. A friend of Mi Fu, Su Shih (蘇軾) admired him and wrote that his brush was like a sharp sword handled skillfully in fight or a bow which could shoot the arrow a thousand "li", piercing anything that might be in its way. “It was the highest perfection of the art of calligraphy”, he wrote.
