Harry Potter spent two extraordinary years at Hogwarts School of Witchcraft and Wizardry. I'm not sure about the specific chapters and chapters because I'm a novel reader and don't have direct access to the Internet. However, as far as I know, the story of Harry Potter spending two extraordinary years at Hogwarts School of Witchcraft and Wizardry mainly happened in the novel series Harry Potter and the Sorcerer's Stone. In the novel, Harry Potter spent seven years at Hogwarts School of Witchcraft and Wizardry, experienced many adventures and challenges, and made many friends and enemies.
