Although Meng Lu is a Miao Witch, their lineage hides away in the deep mountains, avoiding involvement with the mundane world; they do not marry outside, and if they do, the man becomes part of the family and never leaves.
Despite Meng Lu appearing to be in his forties or fifties, his real age is ninety, while Elder Mrs. Meng, who looks older than him, is only over sixty.
Being over sixty allows her to be Grandma to Governor Meng's ancestor, as she gave birth at fifteen, and her descendants also married and had children early, quickly resulting in four generations living together.
In the Miao Witch clan, Elder Mrs. Meng is an exceptionally talented witch, quick to learn everything, but she developed a romantic inclination and met a lost and unconscious Meng Song in the deep mountains during her youth; having never seen another man, she quickly fell for him, even fleeing her clan for him, marrying and having children.
