Goods purchased in the official shopping mall of Chow Tai Fook can enjoy free maintenance and cleaning in any Chinese mainland Chow Tai Fook jewelry franchise store with the commodity guarantee. At home, you can also wash it with toothpaste and water. The maintenance of jadeite also needs proper hydration. Jade will lose some moisture when worn or left for a long time. Soaking jade in water properly at ordinary times can replenish water, and jade can also maintain moist color.
