Here's a short story:

SHANGHAI, China (CNN) -- If it weren't for the Internet, Murong Xuecun might still be working as a sales manager at a car company in the southern Chinese city of Chengdu. That is what he was doing when he started writing his first novel on his office's online bulletin board system back in 2001. 

The Internet is increasingly being seen in China as a tool for literary empowerment, analysts say. 

Week by week when he got home from work, Murong would post new pieces to a story that painted a bleak yet honest picture of modern urban life in the city where he lived. It contained tales about sex, love, gambling and drugs and became so popular that it soon appeared on numerous other online forums. 

Today the 35-year-old is considered one of the most famous authors to have emerged in contemporary China. His debut work, "Leave Me Alone: A novel of Chengdu," has been read by millions of Chinese "netizens" -- steady Internet users -- and adapted for film and television and translated into German, French and English. 

He also is viewed as a pioneer of what has become nothing short of a literary renaissance online in the country, particularly among young Chinese writers. This is a constituency that has struggled to find a platform for their work in a publishing industry that is viewed as conservative as it often faces state censorship. Instead of remaining silent, a new generation of authors has found its voice on the Web. 

"It is a very big revolution," said Yang Hengjun, a political espionage novelist who published his first work online. "When you write something on the Internet that you can't do in reality and you cause a change, that is revolutionary."  (End of story)
