You+ has 16 communities in Beijing, Shanghai, Guangzhou, Shenzhen, Hangzhou, and Fuzhou.

They attracted around 400 million yuan in investment.

Liu saw You+ as just the prelude of youth communities in China. "The supply is still far less than the demand."

Ge Lan, chairman of Mofang Apartments, one of over 1,000 similar youth communities in China, understands that there is huge potential for the market; "China has a floating population of more than 200 million."

The public-house rental sector, including youth communities, is considered by many as an efficient solution for the housing inventory.

Since last year, China has introduced a range of policies encouraging the development of the house rent market.
