The main content of this book is about Harry Potter destroying Horcruxes. Why is the title Harry Potter and the Deathly Hallows and not?

Harry Potter and the Deathly Hallows: Part 2 is the seventh and final novel in the Harry Potter series. The novel tells the story of Harry Potter and his friends destroying the seven Deathly Hallows to prevent the destruction of the world. Although the main content of Harry Potter and the Deathly Hallows (Part 2) is about the destruction of Horcruxes, the title of the book,"Harry Potter and the Deathly Hallows", does not refer to the main content of the novel but to the names of the seven Deathly Hallows. The title was to remind the readers of the importance of these sacred artifacts and the plot of the novel. In the novel, Harry Potter and his friends experienced many difficulties and dangers, but they finally succeeded in destroying the seven Deathly Hallows and saved the fate of the world. Therefore, although the main content of the novel is about Horcruxes, its title,"Harry Potter and the Deathly Hallows," focuses more on the value and importance of the seven Hallows.
