What gift is appropriate for calligraphers?

See how much the other person likes calligraphy, whether he is a professional calligraphy lover or an ordinary one. If he is a professional, he will have professional drawings, many brushes, a lot of paper, a lot of ink, all kinds of stationery and so on. If it is an ordinary lover, he will know what to give. If you are a professional, you have all kinds of tools, and you have seen and used or understood all the good things. In fact, you don't care about what to send, only about your mind, so you can send it at will, whether it's tea or pen and ink.
