From People’s Daily Online:
On July 16 2009, tens of thousands of people became internet friends with Jia Junpeng.
In Baidu’s “World of Warcraft Forums,” a topic titled “Jia Junpeng, your mother is calling you home for dinner” was visited by 390,617 netizens and received 17,028 comments. By the morning of July 18, the post had received over 8 million views and 300,000 comments.
At 1:38 pm on July 20, the post was 10,421 pages long and had received 315,649 comments, reaching the forum limit, preventing further comment.
However, nobody know whether Jia Junpeng exist or not. Maybe, he is just a name created by a joking netizen.
