To upgrade a JD store to a POP store, you first need to meet certain conditions, such as providing high-quality goods and services, accumulating a certain amount of sales and praise rate, etc.

Then, you need to submit an application, pass the JD POP review, and improve the store design, product placement and other details as required. Finally, POP stores need to regularly and continuously update products to cater to market trends and consumer needs and promote continued sales growth. In summary, upgrading to a POP store requires multi-faceted efforts and improvements, and requires long-term maintenance.
