In the process of studying the relationship between artworks and audiences, I am also looking for special audience groups.
Then I thought about art therapy.
If I can use art therapy to help people in need of psychotherapy get good psychological counselling, and at the same time let artworks be sold, wouldn’t it be a win-win thing?
Specific Groups:

This is a group with high similarities. For example, the reasons for their depression are very similar. Most of them are caused by the panic when they became mothers at the first time, the inability to adapt to their own identity conversion, the changes of their bodies and so on.
