If we are talking about China Book Association, as upstairs said, it is unnecessary. Because all kinds of associations with the word China are floating clouds. The people inside are not doers, but so-called guys who "drink tea and read newspapers, and then get paid". The author once tried to join the Chinese Writers' Association (I did have such an idea at that time, and even wandered into their office building), and I knew it was all a cloud.
Let's talk about the local book association.
First of all, your handwriting is very good. Personally, I think it is more than enough to join the calligraphy association. But the problem is that you can't directly enter the general calligraphy association if you write well.
Under normal circumstances, to enter the calligraphy association, you must have entries, that is, you must take your used calligraphy works to participate in the competition. No matter whether you win the prize or not, the materials you take for registration must usually be the works that have participated in the competition, not the ones you wrote on the spot. Then generally pass the exam and pay a little membership fee to enter. Of course, there are also those who don't have to pay the dues.

Finally, I want to give some advice on your calligraphy. This writing is very good, I can't write at your level. But calligraphy is still flawed. You should write more carefully. The single word is almost impeccable, but judging from the layout of the whole text, first of all, these squares are unsightly, and secondly, in a few small places, some words are not very neat. If you look at them line by line, you will feel ups and downs. I think writing is a very simple thing compared with alignment. I think it will be more beautiful if the words are aligned.
