There was a big tree that was always standing alone in a forest. The tree said all day, bragging about how strong and strong he was.
"I am the strongest being in this forest. No one can shake me."

When the wind heard it, he approached the tree with a slight smile.
"Then can I try it out?"

The wind began to blow gently. The tree looked up and flattered.
"I don't care about this wind."

But as time passed, the wind got stronger. When the storm came, the tree couldn't hold on any longer. Eventually, even the deeply rooted tree fell.

The wind approached the fallen tree and whispered.
"Strongness doesn't just come from hardness. It's true strength that you can shake gently."

Next to the fallen tree was a small reed. It was swaying and swaying in the wind, but thanks to its flexibility, the reed was able to survive to the end.
