It takes quite relaxed life attitude, but the current reality is that most Chinese people live too heavy, too wary. Secondly, the Chinese people but also the social reality of a general lack of social habits, no cultural salon, cafe culture, the influence of church culture, friends mostly limited to between acquaintances, also more formally to eat, drink, sing the main, which is directly affect the generation of complex social needs of users on the Internet.
It should also be China's SNS sites similar to the reason why the development of the last places "slave trade", "grab spaces", "Happy Farm" have become such a game to play. China's Internet penetration rate is far from the United States and other Western countries is so high, you want to establish a more common "context" is a slow process. This can also see from the user's Facebook age, although 18 to 44 years old accounted for 73%, but 45 to 54 years old accounted for 11%, 55 to 65 years the users accounted for 6% and in older users have a trend of rapid growth, it can be said that almost do not have the actual situation in China.
