Chow Tai Fook and Luk Fook are both jewelry brands from Hong Kong, and they are well-known in Hong Kong. Because Chow Tai Fook entered China earlier, it is now well-known in China. Liu Fu has branches in the United States and Canada, and has been the exclusive supplier of Hong Kong Sister Beauty Contest for more than ten years, with quite good quality. In fact, the quality of the gold chain is guaranteed, but the style or price is different.
