Some of Doudian's product links have "Safe Purchase" while others do not. This may be because the sellers of these products have reached different agreements and business cooperation models with the Doudian platform.

In Doudian's "Safe Purchase" service, sellers need to promise to abide by the platform's regulations in delivery and after-sales service, and let the platform authorize a third-party agency to evaluate and supervise the seller's store, so as to ensure the interests of buyers and user experience.

Since "Safe Purchase" has higher requirements for sellers, sellers need to meet more stringent conditions to join this service.

Therefore, some sellers may choose not to participate in the "Safe Purchase" service for their own considerations, or have not yet met the requirements. Therefore, some product links will have "Safe Purchase" and some will not.
