Online giants tap into new market

Major Chinese internet players are pumping millions of dollars into building "knowledge-sharing" platforms.

They are all scrambling to entice a new breed of online user that is eager to learn, or be entertained, and is willing to pay for the experience.

Tencent Holdings Ltd has confirmed it will help "content creators" cash in on internet material via subscription fees on WeChat, the country's most popular social media app with more than 900 million active users.
