Mystery******

Okay, I understand a lot of things, but the pinyin makes me a little uncomfortable.

It takes us to explore the mysteries of the universe and understand the magic of the earth and life. Thinking back to my childhood, I was always curious about the unknown. The book mentioned that "the more we know, the more we discover that our unknown areas are larger." This sentence is really inspiring and makes me understand more about the endlessness of knowledge. Recommended to all children who are curious about the world!
