The proceeds from the sale allowed Rowling to move out of the apartment and into a better neighbourhood of Edinburgh.

At first, her neighbors were unaware of the Harry Potter authors in the community, such as biographer Connean Kirk, who wrote, "Most people respected her and gave her space, which was what they wanted." 」

In 1998, Rowling published a sequel, Harry Potter – The Lost Chamber of Secrets, which won her a second Nestlé Smart Bean Children's Book Award, and in December 1999, Harry Potter - The Fugitive from Azkaban, won the award again, becoming the first author to win three consecutive Nestlé Smart Bean Children's Book Awards.

Rowling later declined the award, giving up the opportunity to other books. In 2000, The Fugitives of Azkaban won the Whitbret Award for Best Children's Book of the Year, but did not win the Best Book of the Year award for the Irish writer Seamus Heaney's translation of Beowulf.

The fourth episode of Harry Potter, The Test of the Cup, was released simultaneously in the United Kingdom and the United States in 2000 and broke sales records in both countries, selling 372775 copies on its first day of sale in the United Kingdom, almost as many as the previous game, The Fugitives of Azkaban, in its first year of sales.

In the United States, more than 3 million copies were sold within 48 hours, breaking the book sales record. Rowling admits that there was a turning point in writing the book: "Halfway through the fourth episode, I noticed a serious flaw in the plot, and I had the darkest chapter with the book, and I rewrote it 13 times, and no one could read it and defile it or understand the impact it had on my project. Rowling was also named Author of the Year at the 2000 British Book Awards.

It took Rowling three years to write the fifth episode, Harry Potter: The Order of the Phoenix. This interval had led publishers to wonder if Rowling had cerebral occlusion, but she denied it.

Rowling later admitted that writing the book was a chore: "I thought 'The Order of the Phoenix Society' should have been shorter. She told Leif Grossman, "I know that I ran out of time and energy when I wrote the end. 」

The sixth episode, Harry Potter – The Half-Blood Prince's Betrayal, was released in 2005 and broke the sales record again: 9 million copies were sold in 24 hours.

While writing the book, Rowling told fans online: "I've been working on episode 6 for years, but before I started writing it in earnest, I spent another two months reworking it and making an absolute promise to myself: I know what I'm doing. 」

She notes on her personal website that at the beginning of "Harry Potter: The Betrayal of the Half-Blood Prince", the dialogue between the Minister of Magic and the British Prime Minister was originally planned in "The Mysterious Philosopher's Stone", "The Vanishing Chamber of Secrets" and "The Fugitive from Azkaban".

Year 2006. Harry Potter - The Half-Blood Prince's Betrayal was selected as the British Book Award Book of the Year.

The last work in the Harry Potter series, Harry Potter - The Reaper of Death. The title of the book was published in 2006.

In 2007, Rowling completed the manuscript in her hotel room at the Belmore Hotel in Edinburgh. The book went on sale in 2007 and sold 11 million copies in the United Kingdom and the United States.

Rowling said. When writing the last chapter. When I thought it was "a lot like 1990". The earliest work written in the whole series.

During Rowling's writing of Harry Potter – The Reliquary of Death, she allowed independent television to produce a documentary for her, which was broadcast in 2007. The title of the film is "J.K. Rowling: AYearintheLife."

In the film, Rowling returns to the low-cost apartment she lived in when she wrote The Mysterious Philosopher's Stone, and she cries, "[There] completely changed my life. 」

In Oprah's interview, Rowling attributed the success of the Harry Potter series to her mother.

Now, "Harry Potter" has a global brand value of $15 billion, and the last four episodes of the novel have broken book sales records one after another.

The 4,195-page Harry Potter series has been translated into 65 languages and distributed worldwide. In addition, "Harry Potter" is also recognized as a novel that has revived the reading culture of teenagers who have only used computers and television since childhood. However, the book market continues to decline, and fewer and fewer teenagers continue to read.

In 1998, Warner Bros. bought the rights to the film adaptations of the first two Harry Potter novels from Rowling.

The Harry Potter – The Mysterious Philosopher's Stone was released in 2001 and Harry Potter – The Lost Chamber was released in 2002, both directed by American director Chris Columbus.

In 2004, the film "Harry Potter - The Fugitive from Azkaban" directed by Mexican director Alfonso Coran was released. The fourth film in the series, Harry Potter – The Test of the Cup, was redirected by British director Michael Newell and was released in 2005.

In 2007, "Harry Potter - The Order of the Phoenix Society", directed by David Yates and written by Michael Goodenberg, was released, and it was also the first "Harry Potter" film series not written by Steve Klewood.

In 2009, "Harry Potter: The Betrayal of the Half-Blood Prince" was released, still directed by David Yates, but the original screenwriter Steve Klevu wrote the screenplay instead.

In 2008, Warner Bros. announced that the final chapter of the Harry Potter series, Reaper's Reaper, would be filmed in the first and second episodes. The two films were released in 2010 (Part I) and 2011 (Part II) respectively, both directed by David Yates.

When Warner Bros. contracted Rowling, he accepted quite a few of her requests and suggestions, including that the film had to be filmed in England and that the actors had to be British.

The studios did abide by her conditions, and most of the Harry Potter film actors were selected in the UK. In addition, Rowling demanded that Coca-Cola, which won the rights to advertise its products in the Harry Potter films, donate $18 million to ReadingIsFundamental, a children's literacy organization in the United States, as part of a charitable project.

With the exception of the Harry Potter Secret of the Phoenix films, the rest of the Harry Potter films were written by Steve Klevu, who also received a lot of help from Rowling when writing the scripts to ensure that the scripts did not contradict the content of Rowling's future works.

Rowling has said that Klevo knew the most about the Harry Potter sequel before she released it, but she didn't tell him the whole story.

In the Harry Potter films, British actor Alan Rickman, who played Potions professor Severus Stone, and Robi Coltrani, who played the ranch keeper Roba Hagrid, also received unpublished plot content related to their characters.

As for the British child actor Daniel Radcliffe, who plays the protagonist Harry Potter, once asked Rowling whether Harry Potter would die in the novel, Rowling replied that "you will have a death scene", but did not answer this question clearly.

American director Steven Spielberg once intended to direct the "Harry Potter" series of films, but later gave up. The publisher has repeatedly claimed that Rowling was involved in the process of deciding on the director, but Rowling said that she never intervened in the director selection and did not stop Spielberg from directing the Harry Potter films.

The only time Rowling intervened in the direction selection was when she wanted Terry Gilian, a member of the British comedy group Monty Paison, to direct the film because she was a big fan of Gillen, but Warner Bros. decided that the Harry Potter movie was a little more enjoyable, so it was directed by Chris Columbus.

Even so, Rowling was actively involved in the production of the Harry Potter film series, not only did she review all the scripts, but she also personally supervised the first and second episodes of Harry Potter - The Relic of Death. (To be continued......)
