Principle 2: When people appreciate calligraphy works, the closer the glyph is to the text paradigm, the faster it can be evaluated; Otherwise, it is more difficult to evaluate and more abstract.
Principle 3: Any glyph is a mixture of writing results and drawing results, that is, any so-called writing behavior actually includes drawing behavior.
Principle 4: Writing efficiency is the iron law in actual writing activities and the centripetal force that restricts writing behavior and writing materials.
Principle ⑤: The decisive factor of glyph lies in writing material conditions, not people's aesthetic taste. The material conditions of writing include both tangible constraints, such as writing posture and writing materials, and intangible constraints, such as writing efficiency, stroke direction, stroke order, font size and character arrangement.
