You don’t necessarily need to use your own Taobao Wangwang for Taobao operations. There are many ways to operate Taobao, such as store design, product optimization, event planning, customer service management, etc. These tasks can be completed through the Taobao backend or other software, and do not necessarily require direct communication with customers. However, if Taobao operations require communication with customers, then you need to use Taobao Wangwang, because Taobao Wangwang is an instant messaging software launched by Alibaba Group, which can facilitate Taobao sellers to communicate with customers.
