    For a Chinese kid, publishing(出版)a book in English is quite a big challenge. But Yang Nianhui，a 15-year-old student from Beijing，has done so．

    She wrote all English—language fantasy novel，The Vampires of Lorania．Foreign Language Teaching and Research Press has published it．It is their first time to publish a high school student's works independently．

    In Yang's 60，000-word novel，she describes a vampire kingdom called Lorania．A brave girl named Rose and a Chinese boy fight with bad guys to keep Lorania peaceful. It discusses the meaning of heroism from the view of a teenager．It tells readers，"A hero is one who chooses to stay and fight for what is right，even if he is afraid．"

    Yang studies at the High School Affiliated with Renmin University of China(人大附中)．She has spent over five years working on the book．

    As a big fan of English，Yang enjoys reading original novels and watching TV series in English．She is especially interested in fantasy novels．When she was in Grade 5，she read The Chronicles of Narnia by US author C S Lewis(《纳尼亚传奇》)．It encouraged her to write her own novel．

    With little experience，she did run into some problems，like how to design the story．

    "I read many other fantasy novels to learn some things．And I kept changing and improving my draft again and again．"she said．

    Yang is happy about publishing her first book．"It gives me a chance to express my ideas，"she said．She has already started writing a sequel to her book．
