Hello, etiquette trainers are all engaged in image etiquette after systematic study. Big companies need some image requirements, so the etiquette trainer profession came into being. Generally, they graduated from some image design training schools. I want to introduce you to an Xi 'an Lucy image design training school. It mainly teaches others how to dress, color matching and etiquette knowledge. It is a professional school-running institution approved by the Education Bureau and has a diploma.
