What is the sky ID?

Nothing, is it? Like many Angela, it's just an ordinary id. There used to be a lot, but now there are fewer. Everyone has a name, which is their own code name, and the game registration account also needs an ID. I believe everyone has racked their brains for this. When Bian Xiao was playing League of Legends, he thought of several names that could be occupied, so he had to add a string of letters before the ID he thought of. It's a pity to think of it now, but I've been used to this ID for eight years. The only fly in the ointment is that. But I don't know how you got your ID. Please leave a message to share. What's the short story behind the ID of UZI, Theshy and other professional players? It's interesting to say, because the sky is occupied.
