Go up the mountain with a firewood knife and guess three.

This is the number 325. Chop wood up the hill and sell it down the hill. What we are talking about here is a way, a realm and a state of life.

Every day, I go up the mountain to cut wood and then go down the mountain to sell it. To survive, I make a living. So it's the number 2, chopping wood up the mountain is half of 3, and selling it down the mountain is half of 3, so it's the number 3.
