No, as long as it is related to business, it is related to money. All brands of jewelry will not be exchanged for old jewelry for free, and the same manufacturers and stores will also charge a handling fee. It's just a matter of charging more and charging less. If any brand can be exchanged for free, everyone will buy it. If worn, can it be replaced? So it is absolutely impossible. What merchants call free exchange is relative to other brands of jewelry. Don't believe it. Remember, buy it cheaply. Don't buy thousands of gold, just buy gold. The quality is good and the price is good.
