     Guess who is the most successful young writer in China? It is 24-year-old Guo Jingming, who

earned $ 1.4 million last year, according to the Ne.7u York Times.

     Guo started his writing career in high school when he won first prize in a national writing contest

in 2001. His first book, City of Fantasy, came out soon after the contest and went on to sell more than

1. 5 million copies.

    Almost all Guo's novels include a shy hero who gets good grades. He mostly writes about the sad

feelings of his young characters. These teenagers deal with loneliness by sitting alone for long hours

under trees and on rooftops. "Xiaosi(Guo's nickname), I will always be with you!" A reader wrote in

Guo's blog. "My main goal (目标) is to tell the story well and have everyone like it," Guo said.

     In fact, Guo is seen more as an idol than as a writer. His handsome outlooking, cross-dressing and

strange actions make newspapers pay more attention to himself than his books. Many fans are eager to

get his autograph.

    But today he faces what may be more dangerous threat (威胁): even younger writers. The past few

years have seen the rise of a group of teenage writers, sometimes called the "Post-90s" generation.

However Guo seems to have plans to meet them. Next year, he will hold a national competition for

these rivals (对手).
