This is just the most junior paperhanger who has just started on the road. After that, his back-end technology became increasingly skilled, and his vision continued to expand, and he gradually developed into a paperhanger who could guide other paperhangers. It takes several years to accumulate here. However, I have met a gifted paperhanger. He has a natural aesthetic ability and a pair of skillful hands, and he studies hard. From scratch, it took only 26 days to instruct other paperhangers and even help others open a shop. However, this is an example and cannot be used to illustrate the general situation.
Further up, I will become a master of decoration, research and develop products by myself, improve products, and turn the decoration works in others' hands into wonderful works in my own hands ... This stage requires talent and interest, and needs to study and study day after day, not to mention time.
