The 28-year-old was especially impressed by two mainland entrepreneurs he met in the E Hub.

The young women moved to Shenzhen from Northwest China's Gansu province to develop their 3-D printing idea.

"Everybody works hard on their respective projects," he says.

"We stay in the incubator seven days a week, working on projects, presenting products and exchanging ideas. Such an environment is very helpful."

Hui's dream has transformed from an unpolished idea to a company specializing in expedition travel, study tours and family trips in China and overseas.

The company has also taken 1,170 people from Hong Kong to about a dozen mainland cities.

"Comprehensive views of the mainland enable people from Hong Kong to seize opportunities presented by the country's development," Hui says.

"This provides more space for personal growth. I hope their future paths are in line with national development."
