There are many contents in "100,000 Why". I talked about many aspects, such as: communication, traffic, military, human body, plants, medicine, animals, etc. No wonder his name is "100,000 Why".

I like an article in it best. What is the big dipper? The Big Dipper is the seven stars in the constellation Ursa Major in the shape of a spoon. The two stars of Polaris on the spoon side of the Big Dipper are connected together and extend five times in the direction of the spoon mouth.

When I was a child, I also heard grandma tell the legend of the Big Dipper. After reading 100,000 Why, I think there are many interesting things in nature. Or we didn't find it. So in life, we should be good at discovering and thinking seriously.
