The last hope in the maze
In 1635, several adventurers and geologists searching for treasure lost themselves in a large underground cave in the mountains of northern Europe. When the lights and torches ran out, only the 15-year-old boy who was responsible for leading the animals came out and reached the village alive.
In the cave, the left-handed man has been holding the stone wall with his hands. When he meets the turning, he naturally subconsciously walks to the left, so at the end of the darkness, he finally sees the stars in the sky.
As long as you stick to the left, no matter how complicated the maze is, it will leave you a chance to see the stars again.
Both left and right hands are the same, but because of that event, this method is symbolically described as the left hand rule. It's just a name, without any special meaning.
