To avoid entering brand names on Doudian, you can take the following approaches:

1. Use non-branded keywords to search, such as entering “sports shoes” instead of “Adidas sports shoes”, or use some more detailed features or descriptions, such as “black plush sports shoes”.

2. Use some alternative words to describe the brand, such as “Rolex top watch” instead of “Rolex watch”.

3. You can try to use Chinese pinyin or simplified abbreviations, such as “LV” instead of “Louis Vuitton”, but be aware that it may be considered a brand keyword due to platform regulations.

You can use these methods to circumvent the platform’s brand keyword restrictions in order to better promote your own products. At the same time, you can also consider more information such as the quality and characteristics of the product to allow consumers to better understand the advantages of the product.
