How to evaluate the value of an artist and his works?

To evaluate the artistic value of an artist and the market value of his works, we must first evaluate whether the artist's artistic soul is pure. A respected artist will never have a work that can stand the test of time. Secondly, the artist's tolerance and mind are also the key to determine his works. How can a narrow-minded and vengeful artist help the world? Thirdly, the artist's life experience, social experience and sense of responsibility for the times and society all determine the sensitivity and depth of his thoughts when he creates; Fourthly, the artist's knowledge, including the comprehensive cultivation of humanities, society, natural science and philosophy, also determines the market value and time value of his works of art.

Art criticism, if you don't understand the artist's thoughts, values, attitudes towards life and society, and the creative process, it is impossible to write a real comment: art criticism is a comment on the industry and the future, not just a subjective opinion from the commentator's own point of view.
