Thousands of years ago, in China, there was an emperor, Shi Huang.
He made people from all over China work on the Great Wall.
The work was long and hard.
Many workers died.
A beautiful woman, Meng Chiang-nu, lived with her husband in a small village.
Her husband had to go north to work on the Great Wall.
It was very, very cold in the north.
He was gone for many months.
