This is an old brand. The quality of their products has passed the national quality supervision 3 15. Last year, I went to Chengdu to find my comrades-in-arms and wanted to buy jewelry from Jiuzhaigou. My friend stopped me and took me to Yu He Liunian Jewelry in Dujiangyan. The same product is very cheap for young people and old people. After returning home, a knowledgeable person even said that if I had known, I would have brought one back. It is really profitable to buy products of this quality at this price.
