Why is calligraphy the most difficult?

What you said is too one-sided!

Is it not difficult for space science and technology workers?

Ha. You probably want to ask, is it not easy to learn calligraphy?

Calligraphy-expression also.

Expression is to reveal one's heart through works.

Calligraphy and painting are homologous. Just write like a painting.

Law, law, rules and reason are also true.

But to innovate, we must learn from the past-we must not only abide by the laws and regulations for thousands of years, but also "stick to the rules" and innovate on this basis.

There is a saying called "Literati's Paper". What is shown is the author's personality.

Calligraphy works cannot be used as a tool to make money.

If you want to make money from this, you must not make progress. It is also despised by insiders.

Art is priceless. Therefore, it is very difficult to engage in calligraphy. Really.
