English manuals are not necessarily required. The reason is that although Amazon is a global e-commerce platform, when it sells products to foreign countries, it generally provides corresponding cultural and language services for different countries and regions, so not all products require English manuals. In addition, if the seller has provided multiple language versions when the product is listed, the buyer can also choose the corresponding language version according to their needs. Although not all products require English manuals, it is necessary to provide English manuals for products with special uses or that require detailed operating instructions. Therefore, sellers can provide multiple language versions of manuals when publishing product information to meet the needs of buyers with different needs.
