On Miriam's 9th birthday two years ago, her aunt, who lives in Kenya（肯尼亚）, gave money to a group that cares for elephants to celebrate Miriam's birthday. Then Miriam and her mother visited Africa to learn how the group was helping elephants. Later, Miriam fell in love with the animals and wanted to help save them.

A few months after visiting Africa, Miriam watched How I Became an Elephant, a film about the mistreatment of elephants in Thailand, and a young girl's effort to save them. Miriam decided she wanted to raise money to save elephants.

Last year, Miriam created a program called They Deserve（应得） to Be Free after seeing how young elephants are abused in Thailand. She learned how people take a baby elephant, don't give it food or water for days and beat it hard. "It made me really sad. I need to do something useful." Miriam said.

Miriam is working to make money for Elephant Nature Park in Thailand. She asked her friends to give money to the park rather than giving her birthday gifts.
