If you want to copy Alibaba products to Taobao, you first need to register a seller account on Taobao.

Then, you can find the product you need to copy on Alibaba and copy the product's pictures, descriptions, prices and other information.

Next, create a new product in Taobao's seller backend, paste the copied information into the corresponding fields, and upload product pictures and detail page pictures.

Finally, set the product's price, inventory and other information, save and publish the product. It should be noted that copying other people's products has the risk of infringement, so it is recommended to innovate and create unique products.
