The paper-cutting series of "Old Friend Comes into My Dream" was completed relatively early. It was the third year when I really learned to make paper-cutting. At that time, I already had the idea of ??running a full-time paper-cutting business, but it was not completed due to the interference of some things. In practice, paper-cutting, reading, and writing are still just my spare time. For a long time, I have been a little unwilling and disappointed with this arrangement. After readjusting my mentality, I feel that the current state is quite good.
