Translation:How many fans do you have on Weibo?
I guess the reason it is 'fans' is because the actual Chinese characters 粉丝 fen-si make a sound like 'fans" when they are spoken out loud.
It's a bit sad if people on Weibo see everything like this. Like somehow having many fans makes up for a bit of self-confidence in your own self and your own thoughts and opinions. Also does everybody want to be like a movie or pop star these days?
