Blog is his calling card

JINHUA, Zhejiang - It doesn't take a celebrity to attract half a million followers on a micro blog.

Wang Yujing, a 32-year-old policeman in Jinhua, Zhejiang province, has not only gained popularity, but even helped save another policeman's life by circulating a post.

Wang, a micro-blogger with some 540,000 followers, posted a note last month looking for the donation of an O-type blood liver to save the life of a fellow officer.
