When many of his peers were rushing towards modern civilization, Wang Zhidong, who left Sina in shame 5 years ago, chose to return to the primitive tribe. After launching a new instant messaging (IM) tool Lava-Lava, Wang Zhidong, whose self-styled title is "Chief", announced that he would develop its source code and challenge QQ which occupied the largest market share in the industry.
Including MSN, QQ, GoogleTalk, Skype, Sina UC, NetEase Bubble, Ehuatong and other similar products, there are nearly a hundred instant messaging tools on the market.
