I remember seemingly seeing a sentence that was sent by Aoying.

"You should not care about how many wins you had before.
How much money did you make?
You lose more than you gain.
What exactly is the reason for you?
Do you really understand?

I sincerely hope that everyone doesn't have to learn their lessons the hard way.
but it is impossible

People teach people but cannot teach.
Things teach people once will be fruitful.
