The trainees trained by copying the training mode of western developed countries cannot fundamentally solve the problem of our own image in China. The professional and technical abilities of teachers in many hairdressing training schools are also uneven. Before teaching students, they didn't really understand the head shape, skull, hair quality, hair volume and hair color of China people, so they began to teach students foreign hair-cutting techniques without studying and absorbing them, resulting in many students not using them in hair salons.
