This website is quite familiar to hundreds of millions of Chinese netizens, especially among the young. Some even spend hours on it every day.

It's one of the most popular social network service websites in China, called Kaixin which means happiness.

Social networks utilize free games to attract users. Their major role is a information-sharing platform, which concentrates on holding a stable user group and earning advertising fees.

The white paper issued Tuesday said that in the past five years the online advertisements grew on average 30 percent, with its turnover reaching 20 billion yuan in 2009.

Online role-playing games are also big with netizens. Games like the World of Warcraft and the Fight Among the Three Kingdoms are extremely popular.

The game committee under China's Publishers Association predicts that the number of online gamers in China is expected to grow to more than 90 million by 2013.

According to the white paper, the Internet has become an engine promoting the economic development of China.

It says the government will vigorously promote the development of emerging media such as online radio and online television to satisfy the diversified, multi-leveled needs of information consumption.
