The book aims to immerse readers in traditional Chinese culture and knowledge of the Forbidden City.
The book is thread-bound, with traditional accessories such as a brush pen, a paper-cut, a copper coin and a map dating back to the reign of Emperor Qianlong in the 18th century.
Readers will need to download a mobile phone app, through which they can explore close to 30 puzzles in the book.
Money for publishing the book was raised through crowdfunding. From Oct 24 to Nov 30, the funding reached 20.2 million yuan, breaking the record in China's publishing industry.
Although the story itself is fictional, its 12 alternate endings were written based on 63 books and over 200 academic essays of history and culture from the Qing Dynasty (1644-1911).
Each detail was strictly based on facts in order to let the readers learn more about arts, culture and history.
Wang Zhiwei, an editor with the Palace Museum Publishing House and designer of the puzzle book, said a hidden plot will lead readers to visit the Forbidden City.
"This is designed to enhance the experience of our readers. We also hope the book may instill in readers who have never visited the Forbidden City an interest to learn more about Chinese history and culture," said Wang.
