How did the Lu people in this reading "support the pole" into the city? Is the method of bringing back the dead good? Why?

We must first understand the general idea of the full text.

There was a man in the state of Lu who walked into the city gate with a long pole. At first he stood up and held it, but he couldn't get into the gate. He came and hugged, but he couldn't get into the gate. I really can't think of a way. After a while, Frye came here and said, "I am not a saint, but I have seen many things." Why not use a saw to cut off the long pole and enter the city gate? " So the people of Lu cut off the long pole according to Frye's method.

This is very simple

Stand up first

Cross over again

The way to come back to life is definitely not good.

Can you come straight in right away?

Fortunately, good wood is broken in half, how can it be used again?
