Hi, everyone! I am Mr. Teng Yilin, and my new textbook "Hand-painted Product Design-From Beginner to Proficient" has finally been published! This hand-painted textbook can be described as "ten years of sharpening a sword": seven years of hand-painted teaching experience summary, one year of compilation plus two years of rough publication under the background of the new crown epidemic, a total of ten years of hard work. I hope this book can open the door for basic students to learn hand-painted products and provide help for everyone. Thank you for the invitation and publication of the People's Posts and Telecommunications Publishing House and Digital Arts, and thank you for your support and love!
