When I grew up, my teacher told me that this is
industrial civilization
When I was a child, the stars told me that knowledge is the road to the cradle of the moon:
When I grow up, I know that knowledge civilization is a ladder to get rid of superstition.
When I was a child, my mother told me,
oil lamp
It is light;
When I grow up,
Edison
Tell me, the electrical age is light.
