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.
One day, Meng Chiang-nu went to find her husband.
She walked for days and days.
She walked across rivers and mountains.
Finally, she reached the Great Wall.
Where is my husband? she asked.
Oh, he died long ago, a man said.
We buried him here, by the Wall.
Meng Chiang-nu cried.
She cried for days, and many people cried with her.
Their tears made a river 300 meters long.
