In Indonesia there are various variants of a popular story where two students are arguing over a simple mathematics - like whether 1+1 = 2.
The incorrect student says he will kill himself if he's wrong. They appeal to the teacher, and the teacher punishes the smart student.
I can't find an English version of the story. Here is a translated variant
It's a popular story. In some versions, the teacher was Confucius himself.
I found the story suspicious.
Is this correctly attributed to Confucius?
