In 2020, a survey by the Census and Statistics Department on the Willingness to live in the Guangdong-Hong Kong-Macao Greater Bay Area revealed that over 220,000 individuals were very or quite interested in living or retiring in mainland cities in the Greater Bay Area. Among them, seniors aged 65 and above, including many middle-class individuals, formed the highest proportion. What measures and policies has the government implemented to assist the middle class in retiring in the Greater Bay Area? The domestic market offers integrated medical and elderly care apartments, providing the middle class with rental and ownership options. Elderly residents in the mainland benefit from a more economical lifestyle, saving significantly in food, accommodation, and transportation. Leveraging national healthcare insurance helps offset medical expenses. Furthermore, initiatives such as medical measure provide added medical convenience for Hong Kong residents. With mutual benefits and complementarity between the two regions, it's believed that seniors are presented with an additional retirement choice.
