How can I join Shanghai Hard Pen Calligraphy Association or China Calligraphy Association?

I don't know the situation of Shanghai Book Association, but the basic condition for the general artists association to join is to be selected into three exhibitions of corresponding levels. For example, Shanghai Calligraphers Association, if your calligraphy works have been selected for three Shanghai-level exhibitions, you can apply to join. Similarly, so is the China Calligraphers Association. It is enough to be selected for three national exhibitions.
