First, basic skills
Now you can buy glasses from Danyang and other glasses bases or online wholesale platforms; Management, mainly including clerk management, training, store layout, inventory, activity planning, etc. Publicity, mostly offline, because optical shops basically serve the surrounding people, there is no need to do too much publicity; Shop assistant, open his own shop, usually teach himself skills, glasses and management. They can also recruit shop assistants, but the cost is higher. You can recruit shopping guides and fitting people.
Second, other suggestions.
I have no experience and want to open an optical shop after graduation. I suggest careful consideration. Optical shops have technical and skill requirements, and now the competition is fierce. It is recommended to learn relevant knowledge and skills first, and then carefully consider whether you can open a shop.
