About the origin of the tortoise's longevity, there is such a fairy tale among the people:
Legend has it that the tortoise was originally a beautiful fairy in the sky and was deeply loved by parents. She was shut up in the boudoir embroidery room all day and was not allowed to go out.
One day when she was eighteen, she rushed out of the house alone and wandered in the fairyland. She lost her way for a moment and was arrested by two generals under the Jade Emperor. When the jade emperor saw her extraordinary beauty, he insisted on taking her as his concubine. She cried and made noise and decided not to obey. The jade emperor became angry from embarrassment, turned her into a turtle and gave her a deadline of 1000 years.
She thought that she would rather be a turtle for a thousand years than a doll for the jade emperor. Since then, the tortoise has settled down on the earth.
Crane is a kind of immortal bird with long life. It is said that cranes have infinite life span and are regarded as the king of longevity like turtles. Later generations often use "He Shou", "He Ling" and "He Shu" as birthday words.
