Zhang Wanfu, a jewelry brand in Shenzhen, has done a good job in advertising in Hunan and other places. Chow Tai Fook is the best jewelry store in Hong Kong. Who is awesome? Think about it. This is brand influence. Of course, the greater the brand influence, the higher the added value. Besides, their jewelry is produced in Shenzhen. My previous company produced diamond rings in Zhang Wanfu. Like Nike shoes, they may be made in China or Viet Nam. They only engage in brands, and the cooperation work is not fixed, so they choose the best. If you want to buy a diamond ring, you can order it from the factory here in Shenzhen, and the price will be much cheaper. If you buy it in a nearby jewelry store, you'd better wait for some activities, and the average merchant will make a profit.
