What does the poem Night tell us?

As long as you explore bravely, you can know a lot of things you didn't know before.

Night original:

I used to be timid. I dare not look out as soon as it gets dark. My mother told me that brave story over and over again, but when I looked out of the window, I jumped up.

Dad insisted on taking me for a walk at night, but the flowers and plants laughed like during the day; From then on, no matter how dark the night is, I can see how birds sleep in the moonlight.
