The official flagship store is the enterprise's own store, and other flagship stores are authorized. Taobao has no flagship store, and the enterprises in Taobao are called direct stores.
Generally speaking, Tmall flagship store is not allowed to change its trademark during its operation. This point is also clearly stipulated in the rules for driving cats. Unless the store you run is a franchise store, you can add other brands and then authorize the trademark change. If it is not a franchise store, you need to communicate with Taobao Mall and try your best to win the right to change the trademark. Anyone who has opened an online store knows that Taobao Mall will require merchants to provide a trademark processing notice when entering the store. If the merchant wants to change the logo or trademark after registration, it needs to be decided according to the regulations of Taobao Mall and the settlement agreement signed with the platform.
