No. Chow Tai Fook is a well-known jewelry brand, and its official website provides online shopping services for jewelry products. Ups and downs are terms of financial products such as stocks and futures, and have nothing to do with jewelry products. Therefore, the ups and downs on Chow Tai Fook's website should refer to the price changes of jewelry products, not the ups and downs of financial products. The price of jewelry products will be affected by many factors, such as materials, technology, market demand and so on, and price fluctuation is a normal market phenomenon. If you buy jewelry products on Chow Tai Fook's website, it is recommended that you read the product information and purchase terms carefully to understand the price and quality of the products and avoid unnecessary economic losses caused by price fluctuations.
