11 Yao Yao battle platform, how can I create a name that stands up?

This is simple. Just add |n after the name, and it seems that only two-word names will do. For example, the shadow demon is the "shadow |n demon". You can't see it yourself. You can only see it from other computers. When you turn black, you can try to see that your name is vertical on your friend's screen. I have helped my friends get several such numbers.
