What is the jewelry market mentioned in the CCTV2 [Consumer Proposition] program "Buy Diamond Ring for Great Value"? Where is the specific location?

Beijing Youwante Jewelry City, get off at Jishuitan Station, No.57, Xinjiekou North Street, Metro Line 2, exit C, southbound 500.

There is Tianya Jewelry City, 3rd floor of Metro Line 5, exit A of East Gate of Temple of Heaven, northbound 100 meters, behind Hongqiao Market.

I hope it's not too late.
