This giant market peddling jade and other semiprecious stones is under Jianguo Overpass. There are also beads, pearls, religious artefacts and copper teapots. Some stalls allow bargaining. Just south is a weekend flower market that smells heavenly and has some fine examples of bonsai bushes and orchids of many colours.
To get here, walk in through the flower market where Jianguo Overpass meets Xinyi Rd.
