A growing number of Hong Kong residents are moving to the mainland to work, live and study.

In April, Chief Executive Leung Chun-ying revealed around 300,000 Hong Kong people like Cheung are working on the mainland on long-term contracts. The figure is equivalent to 8 percent of the city's total labor force.

Many recent arrivals are young entrepreneurs.

The Youth Innovation and Entrepreneur Hub－aka the E Hub－in the Qianhai Shenzhen-Hong Kong Modern Service Industry Cooperation Zone had incubated about 50 entrepreneurial projects by people from Hong Kong as of the end of October.

The number is expected to grow.
