You can act as a calligrapher. If you are a folk professional selling calligraphy and paintings, you can slightly increase your reputation. The price is about the same as if you are not a member of the Municipal Book Association, but it can be increased by less than 10, right?
If you run a youth training class and your calligraphy is really good, your appeal will be much stronger than if you don't have any reputation. Really, I'm telling the truth, I'm an insider too. I hope you will be satisfied with my answer.
With a reputation, you can communicate with more high-level people. It is more beneficial to you when doing work related to calligraphy and painting.
