You can choose to add them separately. The products on Douyin are sold as products on the Internet e-commerce platform. When consumers shop on the e-commerce platform, they can add the products they like to the shopping cart, and then pay the corresponding merchant. After the payment is successful, they can wait for the merchant to ship the goods. Since the purchased products correspond to the order information such as the payment price. Therefore, if the product has multiple specifications and you need them, you have to add them separately.
