What is the "God" in calligraphy?

Spirit is divided into two aspects: 1. It is the so-called spirit likeness, that is, in the process of copying, after reaching the shape, continue to practice, so as to achieve similarity in expression, which can be achieved by increasing the number of copying. It is reflected in the strength of each stroke, the avoidance of structural arrangement, the center of gravity, the width, etc. The density of composition is the expression of spirit. 2. It is an unrepeatable mental outlook naturally formed through long-term accumulation and personal experience. As the old saying goes, the words are as they are, and everyone's habit of summing up words is related to personal cultivation and pursuit. There is a saying: temporary posts can never be completely similar and can never be completely different.
