I bought it in a shopping mall or a regular store, and I have the receipt. If there is no damage, you can get a refund. You can try. Jade is a special industry, and it is generally returned. Because, once you call the 3 15 industrial and commercial complaint telephone number, you will check their purchase and sale vouchers, but due to channel problems, there is no invoice for buying jade. Because of fear of trouble, it is usually returned.
