Chaohongji is a large-scale enterprise that mainly designs, processes, produces, wholesales and retails platinum inlaid jewelry, while Shipin focuses on the jewelry industry. If you are interested in the manufacture and sale of platinum inlaid jewelry, Chaohongji may be a better choice. If you pay more attention to the jewelry industry, then Sprin may be more suitable for you.
Generally speaking, which company you choose depends on your career planning and personal interests. I suggest you have a deep understanding of the business, culture, products and services of these two companies, and then make decisions according to your own needs and goals.
