But no, she's the goddess of longevity.
But I guess youth, beauty and health can certainly make one happy!
"Ma Gu, the goddess of longevity in ancient Chinese tradition, always appeared as a young and beautiful maid of eighteen. According to the legend, Ma Gu lived tens of thousands of years, achieving longevity by picking divine herbs from a verdant forest and brewing wine with them. Legend also has it whomever tasted a cup of Ma Gu's wine would be eternally young, beautiful and healthy.
According to legend, MaGu lives forever on clouds. Winter Blooming Dergenia, with a soft cloudlike texture and form have been planted around the statue."
