Many families like to decorate with glass, which is not uncommon in kitchen decoration. Traditional folk culture believes that when decorating the kitchen with glass, we must be careful, especially when hanging mirrors in the kitchen, which is easy to bring bad meanings. When the mirror shines on the fire, it will increase the chance of fire or misfortune because of its reflective effect. Moreover, the reflection of the mirror will make two stoves appear in the kitchen, which symbolizes the hostess in the traditional folk culture, which means that there will be two hostesses at home, which will cause family disharmony.
