The CEO of Sina.com, Cao Guowei, announced in February that Sina Weibo had 503 million registered users by December.

Huang Lijun, 31, a senior member of the Teamtop Training Institute, in Guangzhou, says that the micro blog boom makes contacting human resources managers in various fields a lot easier, and they can provide the latest hiring information and even inspire applicants by interacting online.

In support of this, Zhang Jie, a supervisor at Ctrip.com International Ltd, China's largest online travel agency, says, "In traditional hiring, corporations have to sit around waiting passively for applications. But, with the micro blog, we can communicate with them directly and promote our position at the same time."

Zhang goes on to explain, "Hiring is becoming more like sales, the only difference being to promote a product or a corporation. So, we have to do it many ways, the same as we do with sales. The micro blog has a huge number of users. How could we ignore it?"

Zhang began posting Ctrip's job information and popular career topics on their official job account in February and some applicants sent their resumes via a micro blog message, and he in turn recommends suitable positions for them.

In commenting on this, Teamtop's Huang says, "The microresume has great potential because few people are using it so young people can show their talents in a fresh way," adding, "Anything that is rare is precious. If an HR representative sees a micro blog resume, he or she will definitely take note of it. If there are hundreds of these resumes, HR people prefer reading those applications in their e-mails."

He himself spends about two hours on his public service micro blog to repost and provide career tips for new graduates as well as explaining job-hunting and interviewing skills, career planning, and office etiquette.
