Fairy tales have been an essential ingredient in children's literature. Canonical fairy tales passed down from generation to generation not only enrich children's imagination but connote significant values typical of the community. However, as time passes, contemporary writers often challenge these traditional values when they work on the same topic. This changing face is evidenced by Emma Donoghue's rewriting of classical tales. Based on my teaching of Donoghue's story 'The Tale of the Bird' alongside Andersen's 'Thumbelina' at a university in Hong Kong, this paper discusses the ever-evolving cultural values and the benefit of reading Donoghue via Andersen or vice versa in the literature class and beyond.
