Why can't some brands be found in Tik Tok's Netease, YEATION, Vipshop and Taobao?

Vipshop will have some big brands that specialize in cooperation, but not all big brands will cooperate in Vipshop.

Vipshop and Tik Tok's e-commerce platforms are two different e-commerce platforms, with different sales stores, purchase channels and commodity sources.

Therefore, it is very normal that the goods that can be found on Taobao cannot be found at Vipshop. Originally, the positioning of the two e-commerce platforms was not the same. This differentiation has always existed and is very obvious.
