With only a click of the mouse,rumors   can be forwarded between microblogs very quickly.As an example,recently,sensitive netizens discovered that some photos displayed on microblogs describing Beijing's June rainstorm had actually been fabricated. Sina.com is one of the major Internet portals in China with hundreds and thousands of users,and a majority of celebrities and famous citizens have their microblog accounts on this portal.As recently as six months ago,the website decided to establish a specialized team to prove rumors and provide accurate information for its users.Tan Chao is in charge of the team. "Before I took the job,I usually couldn't identify what information was real and what was fake.But during the process of identification,we discovered that a lot of information was false,including fake photos,fake news stories and rumors that had been spread through microblogs." It's not just website portals which are taking on factchecking responsibilities,but also a number of civicminded netizens,who recently set up a Rumor Identification Federation on Sina.com's microblog system to help netizens identify fake information online.

Some experts say this displays the advantages of the Internet compared to other traditional media.The open platform allows information to be examined and clarified by netizens.But experts like Ding Wenguo,President of the Journalism and Communication College at the China University of Political Science and Law says this selfcorrection function of the Internet is still quite limited. "It's still quite difficult to tell which information is true in such an open environment by just reading a number of different opinions on the same issue.This is something which we need to pay attention to.If society is flooded with too much false information,and it's allowed to spread in such a fast manner,then people will be suspicious of all kinds of information including important information from authorities.It also worsens problems relating to social communications and mutualunderstanding,which in turn harms society as a whole." Experts suggest that the government should react more quickly in the Internet age.Once a rumor begins to spread,administrative departments should make announcements as early as possible to drive away rumors before they lead to bad outcomes.
