It's true. It's really good. Last month, I went to Chengdu to see the children. By the way, I visited Yu He Liunian Jewelry in Dujiangyan, Chengdu. It looks very tall and quite classy. There is also a teacher on the fourth floor who has given a lot of knowledge about jade and jadeite. Although we have no intention of buying, the shopping guide is still very enthusiastic and impatient. Teacher Wang is too dedicated.
