Hello, dear, according to what you said, Centennial Tongxin should be the name of a jewelry store, and its gold should be the brand of other companies. Of course, as long as it is pure gold and does not pay attention to brands, it is also possible to choose a hundred years of concentricity. The cost of small shops is lower, and the cost of personnel and venues will be lower. The price will definitely be more favorable than others, otherwise he has no competitive advantage. As for other brands, it is expensive because of the added value of his brand, that is, her reputation is greater than that of ordinary brands, not because gold is necessarily better than that of other companies. The above is the reference for you to answer Nomon Jewelry.
