1. Direct mode: Ling Bao jewelry adopts direct mode, with point-to-point sales, no intermediate links and basically no intermediate costs. In contrast, joining a brand needs to pay the joining fee, management fee, marketing fee and markup fee of the brand headquarters, and the relative cost is higher, so the price will be higher.

2. Direct Supply: Ling Bao Jewelry is a Hong Kong-funded company. Direct supply reduces the number of intermediate dealers, thus making the price more competitive.

3. Small profits but quick turnover: The marketing strategy of Ling Bao Jewellery is small profits but quick turnover, so as to obtain lower purchase cost through mass sales, thus having more advantages in price.

To sum up, the main reason why Ling Bao jewelry is relatively cheap is its direct selling mode and direct supply marketing strategy of small profits but quick turnover.
