Analysis of the Pros and Cons of Taobao Sellers Establishing Customer QQ Groups

In the aspect of online store promotion, I personally think that it is much more worthwhile to maintain good relationships with old customers than to develop new ones. When my Taobao Experience blog was first created, I wrote an article about how to use QQ groups to maintain relationships with old customers. Later, I posted this article on other websites, and people had different opinions about it. Of course, most people said the method was good, but some people did not look favorably upon this method.
