Once upon a time in ancient China there was a poor peasant farmer called Bolin which means 'gentle rain'. He was in love with the princess, Soong Ching-Ling, but they were forbidden to marry because he was part of the Nong society  and she was a rich Princess. 

Do the royal task!

The Emperor Qin decreed that if any man wanted to take his daughter's hand in marriage he would have to achieve a royal task. The royal task was to bring his daughter the moon. 

The first suitor brought the princess Soong Ching-Ling a beautiful piece of stone and presented it to her as the Moon. 

"No! That is not the moon. I will not marry you!" She pushed the gift away. 

The second prospective husband brought the princess a painted picture of the moon with a black starry background.

"No! That is not the moon. I will not marry you!" She pushed the gift away. 

Bolin presented the Princess with a glass bowl full of clear water. The princess studied the bowl and noticed a reflection of the Blood Moon. 

"You have brought me the moon! You have accomplished the royal task. I will marry you!"
