The nickname Wu Gou is really too common. For people like Gu Yu, who frequently follow Wu Mu's updates, they've mostly gotten used to it, so they didn't immediately realize there was any issue.
Besides, they're speaking up for you right now. Who cares about calling you a dog at this point? Weren't you already known for being quite dog-like?
Gu Yu was silent, while Mo Mo laughed and covered her face, saying, "Teacher Wu Mu, aside from your fans, who actually calls you by your name anymore? You just have to accept it."
Compared to others, Zhihu is still relatively kind. Outside, it's pretty much taken for granted that anyone who doesn't call you Wu Gou is a Wu Mu fan.
Yep, it's a recognized slang term in the industry, used to distinguish different types of followers.
Calling him Wu Mu means you're a domestic fan, Wu Mu ge means you're a Korean fangirl, Mu Mu chan means you're a Japanese fan, and Wu Gou means you're just a passerby or a spectator looking for fun.
