Straight after the publication details there is a synopsis of the story of Harry Potter and the Porcelain Doll. The following is the synopsis in Chinese, with a rough English translation.
Harry is highly worried to learn that Voldemort is going to China to find his Oriental nemesis, Yan Dao Mo, in order to counter him and threaten the entire Western magic world.

Harry is overjoyed to learn that Long-Long is the Eastern Prodigy 'Dragon Champion' and Xing-Xing is the Eastern princess 'Sandalwood Star'.
