五代的名画家荆浩,在他的《笔法记》里说:“凡笔有四势:谓筋、肉、骨、气。笔绝而不断,谓之筋;起伏成实,谓之肉;生死刚生,谓之骨;迹画不败,谓之气。”如果进一步解释,则当为: 笔断而势连、迹断而意连,有弹性、节奏、力量,在感觉上能如春蚕吐丝、连缀不绝的为筋。 Jing Hao, a famous painter of the Five Dynasties, said in his “writing method”: “All pens have four potentials: the ribs, the flesh, the bones, and the qi. The pens are continuous and continuous, and the ribs are the ribs; the ups and downs come true and the flesh is called; Life and death have just been born, that is to say the bone; unbeaten traces of the painting, that the gas. "If further explanation, then it should be: broken and connected, trace off and intended to connect, flexible, rhythm, strength, in the sense of Spring silkworm silk, endless ribs.
