Many of Liu's renters start their own business at the community. Some of them are busy day and night. "They do not need to jam into the subway and go to the office to the other side of the city," Liu explained.
Wei Jialin, 26, used to live at the You+ community in 2015. She said that the biggest difference between a private apartment and the youth community is being able to make friends.
"I don't want to sit in front of computer all day night," she said. "It's not what young people should be doing."
Wei works on an overseas study program service now. She met her boss and colleagues at the same youth community. "Most are outstanding entrepreneurs who helped my career a lot," Wei said.
Liu Yang believes that his community is safe. "Any unfamiliar face is recognizable," he said. "All the door-entrance buttons are hidden; only members know."
There are around 10 maintenance and communication workers in each You+ community.
One resident had an angina attack. "Many members rushed to his aid after they heard about it on WeChat."
By the time the ambulance arrived, the ill resident was out of danger, thanks to his friends. According to Liu, all the residents are unique and can make their own contribution.
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.
The Central Economic Work Conference at the end of last year encouraged people to buy-to-rent. While enterprises such as You+ and Mofang are also encouraged to manage tenants.
