The latest blueprint of the Guangdong-Hong Kong-Macao Greater Bay Area is to better facilitate free flow of talents among the three regions.

A blueprint of the Greater Bay Area was unveiled on Monday. It outlines short-term plans through 2022 and long-term policies for 2035. It encourages Hong Kong and Macao residents to study in the mainland schools or work in state-owned enterprises or even government agencies.

Rocky Yu, a Hong Kong citizen, came to work in Shenzhen City, in south China's Guangdong Province 16 years ago.

Yu says when he first came to the mainland, he couldn't get used to driving there, because people drive on the left side, while in Hong Kong it is the right side. But now he can drive quite well.

Yu runs a business service center in Shenzhen, providing consulting services. He has helped more than 200 Hong Kong companies in the mainland.

Yu says Hong Kong businessmen couldn't get used to doing business in the mainland as the taxation system and business registration procedures there are more complicated than in Hong Kong.

"Hong Kong businessmen couldn't get used to it at first, because they were required to have tax registration and license for opening accounts in banks," said Yu.

But he says things are improving. Having been living in Shenzhen since 2003, Yu has seen positive changes, like a number of preferential policies for those working in the mainland.

"We used to need a temporary residence permit, but now we don't need to apply for that," said Yu.

Many people work and even move to the mainland from Hong Kong or Macao. There are concerns the workforce flow from the mainland will become a problem of imbalance of human resources, but some experts are not worried.

"I think the imbalance here like the human resources exchange between Hong Kong, Macao and mainland is the policy difference here. If they make favorable policies for the mainland people working in Hong Kong and Macao more easily, I think this can be solved in the long term," said Liu Chunsheng, an associate professor at the Beijing-based Central University of Finance and Economics.
