Yes, yes, Amazon does not have customer service. We only need to upload products, optimize them, and ship them after they are sold. Buyers on Amazon are also relatively simple. Most of them will place an order directly after choosing a product. If they have any questions, they will also send you an email. Our email replies are translated. Even modern browsers can translate into Chinese. Our store operation process is all in Chinese interface, so not knowing English will not have much impact on Amazon. Many of my students do not know English very well, but they are doing pretty well on Amazon now.
