Default rules for product upload: Products are displayed in the order they are uploaded, with later uploads prioritized for display (e.g., the first upload appears last, while the latest upload appears first). To specify a custom order, modify the product numbering—higher numbers will be displayed first. After adjusting the numbering, click 'Sort' to apply the changes. For special products requiring top placement, use the 'Pin to Top' feature directly.
