China is an amazing versatile country, with 100k accomodation facilities being built in Shanghai per month, then you can see the growth is astronomical. Rather than use platforms in existence in the west, due to firewalls, legal internal focus the Chinese build their own. Below is a comparison chart of Chinese social media channels compared to the ones we use here in the West put together by Dr Matt McDougall, Chief Executive Officer for SinoTech Group, a digital consulting firm based in Beijing.

From what the slide shows, the social media landscape in China is much more vibrant, albeit fragmented than what people in the West are used to, this is mainly due to the large scale nature of the country, with networks being built for regions rather than for the country itself as each region has varying requirements and needs.
