The gold ring you bought is easy to return because it is not for sale. The big deal is to change the shape, but the platinum ring I bought is really difficult to return. Why? Because not many people buy platinum now. Selling one is another. He made money and can't pay you back. You really can't do it. You can only take a step back and exchange with him. But he doesn't like to exchange gold with you yet. So, this is a status quo. What about the jewelry industry? There are many hidden pits. Nothing you can do can stop it. You fell into the pit. What can you do? Therefore, we can only accept this reality helplessly. If you communicate well, you may be able to quit, but if you communicate badly, you can't quit completely.
