Drum tower and ancient cultural street are both ok. You can draw a price if you are optimistic. In addition, the jade counter on the first floor of Gloria Sai Commercial Building in Hongqiao District can also be used, which is much cheaper than big shopping malls. I also like jade ornaments. I bought it in these places. According to the seller himself, jade is really valuable now, and you can bargain with the store according to your psychological price.
