You can go to the 109 wedding building opposite Xidan shopping mall. There is a jewelry hall on the third floor with jewelry processing and production services. The specific location is in the north of Xidan shopping mall, southwest corner of the intersection, Xixi Friendship Hotel. You can tell at a glance. This is a big building with huge advertisements on it, which is easy to find. I feel that the craftsmanship inside is ok and the price is not expensive.
