Some stories around me reminded me of something, so I turned on the computer and entered text. The name came to me suddenly because I accidentally made a Mobius ring to play with that day. It turned out that this thing is very interesting. You can go directly from the front to the back, a plane without a back, a plane where good and bad are in the same direction. Just like in life, you can never tell who is right or wrong in some things, and you can never understand who is good and who is bad.
Maybe good is bad, and bad may not be bad. In short, it is like a black hole that can never get out...
