Which stars have opened WeChat?

There should be many stars. As far as I know, articles, Ma Yili, Sun Li, He Jiong, Li, Nana and so on are all useful. These are what I said when I watched their interviews or programs. Stars are human beings, and they can also use the software we use, so there should be many. But you don't know which one is them. Even if you do, don't bother them. Stars are people, too. They don't chat with strangers, do they?
