I don't know the purity, but the waiter of this brand of Tiantongyuan Xidan Store has a very bad attitude. My wife bought a gold jewelry at the end of last year, and there was a very obvious crack in less than two months. I went to the store to return the goods. That attitude is really flattering ... because I was careless, and my wife never had any problems with the gold ornaments she bought before. I always believed that the gold ornaments were made of gold and there would be no problems, so I lost the invoices and receipts when I bought them. But because of the short time, when I returned it, the lady who sold my gold ornaments was also there. I think it should be easy to communicate. I don't think she will not return it after communicating with an elderly lady. Looks like a store manager with a stiff expression and strong muscles. These words are full of meanness and rudeness ... finally, they are soft, and they cost 20 yuan per gram ... think about yourself. Buying a piece of jewelry should have added some joy to the plain life, but it was ridiculed, ridiculed and made things difficult by the brand clerk for no reason ... Now I think about it, my intestines are regretful. Here I advise you that expensive things will still be big brands in the future.
