The difference between a deep reader and a connoisseur.

1, the job is different. A calligrapher's profound accomplishments are his nickname, and his job is to promote calligraphy. The connoisseur's job is to identify and appreciate cultural relics and works of art.

2. The description is different. People who have a deep understanding of books buy back the great power of calligraphy from the inside, while connoisseurs describe people who have superb appreciation of things.
