There are still quite a few users of the Extreme Edition, and people of all professions have it. I used to make friends with acquaintances, so I can chat on them if I have something. Then there is an epidemic. None of our company goes to work. We are all talking about having a meeting every day, and colleagues will add a good friend. I also have a friend who makes clothes. She will also use the chat number to invite customers to add friends and buy and sell things. It is quite convenient to build a group on it, and a lot of transactions have been made.
