Manchu people have always had the custom of worshipping willows. They worship the vitamin god, Liu is their ancestor and vitamin is their mother. Frodo's mother is in Manchu, Frodo is the prefix of Frodojo in Manchu, and it means willow in Chinese. Mother means grandma, old lady and queen in Chinese. Frodo's mother translated it directly, meaning Grandma Liu and Queen Liu. Sacrificing to Frodo's mother is to have a full house of children and grandchildren, which is related to the deep-rooted willow, its love for life and its rapid reproduction. So Manchu also called Frodo's mother a descendant. Chen Manchu is a family, descended from Abu Kahehe, but it has long been a tribe, and everyone has his own surname.
