Yun Yifan's mechanical design course is not bad. Fan Yi Education belongs to the brand of Yunzhongfan Education, focusing on cultivating interior design talents. At present, there are many training institutions for interior design in China, but few really train designers. Most of them just learn a few necessary softwares, lacking the necessary explanation of interior principles and the cultivation of artistic creativity in interior design. Designs without creativity and connotation are easily copied or compared by others.
