As the ancients said, words are like people. Can you really see a person's character from calligraphy?
Well, you should have heard that comment. People who practice calligraphy will have a temperament that others don't have after a long time. However, this temperament is different for every calligrapher. People who are arrogant and straightforward are generally firm, and smooth people often deal with it everywhere when they are on their arms, so my personal opinion is that you can really see a person's personality, but it still depends on the insiders. This is just my personal opinion.
