1. Jewelry Store: You can go to the local jewelry store and find an experienced store to inquire about the transaction. Shopkeepers will know the market and can offer reasonable prices.

2. Auction house: If the quality of dzi beads is high, you can also choose to hand them over to the auction house for auction. The auction house will have a professional appraiser to evaluate the dzi beads and choose the appropriate auction method and price for them.

3. Online trading platform: You can also choose to sell dzi beads on some online trading platforms, such as Taobao and JD.COM. These platforms will have a relatively complete trading mechanism and can provide a safe trading environment.

It should be noted that no matter which way you choose to sell dzi beads, you need to conduct professional appraisal and evaluation of dzi beads to ensure the fairness and legality of the transaction. At the same time, we should also choose a reliable trading platform or merchant to trade in order to avoid fraud or other unnecessary losses.
