"I understand the 'transient' and 'precarious' feeling of living in an unknown city," Liu, 42, said. His own experience inspired him to provide young people with a real "home," and somewhere they could kick-start their career.

Young people do not often communicate with their neighbors since they are busy working so hard, Liu said.

"People are uncomfortable in an unfamiliar environment," he said. "Thus, safety comes in numbers."

"Home means warm, safe, and stable," Liu said. "Our You+ community is grounded in these concepts."
