Ancient China: Song dynasty
960-1279
Like the Han and the Tang Dynasties, the Song Dynasty was
a time of wonderful invention and art. Chinese opera
began during this period, as did the art of paper
cutting.
So many things were invented during the Song Dynasty that
this period in history is sometimes referred to as China's
Age of Invention.
Legend says ... Out of all the wonderful things that Marco
Polo discovered in the Song Dynasty, he was most most
impressed by the fabulous new creation, the Rainbow
Bridge.
It was called the Rainbow Bridge because of the way it was
bent - in the shape of a rainbow.
