What do grandma Moon Mark mean by those two sentences?

Desire for good things. Grandma said that the moon was a osmanthus tree, because women in that era basically didn't go to school and received little education, and the moon looked like this with our eyes, with light and shade. It means that many beautiful legends about the moon have been handed down out of longing for beautiful things. For example, there is a laurel tree on the moon, where the beautiful Chang 'e lives. There are jade rabbits around Chang 'e, and sometimes Chang 'e is still dancing.
