Mirumoto Hatsu was invited by a friend of his to be teacher for a day to his friend's student Matsu Chinojo. Hatsu told Chinojo to show him his stance, which Chinojo did, then told him to relax. Again Hatsu told Chinojo to show him his stance, but this time Hatsu struck Chinojo as he was entering his stance. Chinojo had been too preocupied with entering his stance he had not noticed the Mirumoto attacking him. Hatsu said; "Your mistake was showing me something you had shown me before. Never show your opponent something twice, for if you do you are lost."
