some suggestion

4.1 Suggestion for real estate sectors:
(1) choosing rural area
It is crucial to build retirement communities in rural areas. Since cities are narrow and noisy with countless buildings, construction and traffic, the environmental situation is not quite suitable for the elderly to live in. Additionally, property values in cities are more expensive than those in rural or outlying areas. To save on investment costs for retirement communities it is better to establish them in rural areas. This approach could also generate a profit in another aspect by creating an attractive spot for a retirement community to build a tourist hotel at cornerstone part of their region. Harnessing good quality or an eco-friendly surrounding should help to relax both the elderly and tourists from other visiting cities or countries. However, this may mean more administers to keep the elderly and the tourists away from each other to avoid possible conflict. So it is just one option out of many others to develop a beneficial retirement community.
(2) perfect function
To ensure that retirement communities are completely functional to serve all the people in it. Because retirement communities are built in rural regions, it may mean the social functions of commercial buildings such as supermarkets, cinemas, gyms and other public architectures cannot offer their service to these retirement communities. Therefore, it is important that when the designs of retirement communities commence, a range of suitable functional buildings should be planed accordingly. Case in point: The Sun Center in American has shops, golf sites, swimming pools and other facilities in vicinty of their retirement community. And not only are commercial buildings are needed but also nursing care buildings like hospitals, medical centers and sanatoriums are required.
