You can enter the Product Selection Square after opening a store. The Product Selection Square is a product selection channel provided by Douyin e-commerce for merchants. Merchants can select products suitable for their own stores here and add them to their own stores for sale.

If you cannot enter the Product Selection Square after opening a store, it may be because your store has not passed the review or has not completed the relevant settings. You can check whether your store has passed the review and whether the relevant settings have been completed, such as store information, product information, etc.

If your store has passed the review and completed the relevant settings, but still cannot enter the Product Selection Square, you can try to contact Douyin e-commerce customer service for their help.
