Crystal shop, Binbin Crystal? It's the biggest in his family, and there are several smaller ones. Binbin Yao devalued the crystal that customers bought from other homes, and the price of his own home was reported indiscriminately. Novices who don't understand will be severely slaughtered.
What impressed me the most was that when I went to buy opal, he took out a piece of all-green white opal, saying it was high-grade goods and the best, and that he studied jewelry appraisal, which really made me want to scold my mother. Green is high-grade goods, so what are fire opal and black opal?
