Unity of knowledge and action. (You must know Chinese characters, and have a sense of appreciating and belittling their shapes.)
Followed by cultural and literary accomplishment (inexplicably like Beijing opera, Chinese painting, Chinese medicine, poetry, ancient prose and so on. But the artistry of calligraphy is most afraid of religion, politics and economy. I am even more afraid of touting and hype with ulterior motives besides narcissism and love at first sight. Artistic sense is a kind of ability-based silence when experts meet laymen.
Secondly, I believe that practice makes perfect, and learn to write my feelings in calligraphy so that others can love me.
The love of others is a kind of dazzling of laymen. Different levels, different attainments, different years and different occasions. Never love the new and hate the old, and scholars despise each other. The life span of all cultures is determined by the vulgar, and the love of the people is the real lesson of innocence.
What a talker! However, it is definitely an experience.
