Children ask me why copper bells are hung in front of western restaurants and red lanterns are hung in front of Chinese restaurants. How can I explain this clearly?

copper bells are hung at the entrance of the western restaurant, which is to serve foreign things. Copper bells are actually geomantic instruments used in ancient China, mainly used by Taoist priests, monks and other religious people, and later borrowed by ordinary people to ward off evil spirits. Hanging red lanterns at the entrance of Chinese restaurants has long been used to exorcise evil spirits and create a festive atmosphere. Now hanging red lanterns is mainly to create a festive atmosphere.
