"Niels Riding a Goose" The elf promised that as long as Niels, what would become the same person?

The elf promised that as long as Niels brought Morton the goose home and let his mother kill Morton, he would become the same person again.

Niels was turned into a little man with a thumb by the elf because he played tricks on the elf. Finally, the elf promised to make Niels a normal person on condition that Morton, the goose, must die. In order to save Morton, Niels gave up the chance to be a normal person again, but when Niels' parents saw him again, they were surprised to find that Niels had grown tall and become handsome. Only then did Niels find himself finally a normal person.

The creative background of Niels's Goose Riding Journey;

1887, a teacher's college dean named Darling asked Selma, who has been a geography and history teacher for a long time, to write a book that primary school students like and introduce history and geography to Swedish children. When she writes, she has a clear intention in mind: "to educate Swedish children to love their motherland."

From the perspective of pedagogy, she believes that "children can truly love and respect their motherland only if they know their own country and are familiar with its history". This long fairy tale was actually published as a variant of a textbook.

Many of the author's works are set in his hometown, and the conception of this fairy tale is also inspired by her walking experience: once when walking in the garden, the author was startled by the sound of "help" from the urgent voice, and a little boy was struggling to resist the owl that pecked at him. This scene left a deep impression on the author. Later, this picture is the scene where Niels, the heroine of her fairy tale, often bullies chickens, ducks, cats and dogs at home and is attacked by animals.
