The Yangtze River Delta has been a rich land in the south of the Yangtze River since ancient times, and the Pearl River Delta is also a region rich in products. Because the two regions are economically developed, there is little difference in transportation facilities, urban construction, food culture and medical conditions, so the comparison of old-age settlements is more from climate and environment.
The Pearl River Delta region is a subtropical maritime climate, and it is one of the regions with the smallest annual average temperature difference in China. Winter, autumn and spring in the Pearl River Delta are relatively short, and nine months are summer. In the Pearl River Delta, it is basically summer to take off your coat. I think it's better to settle down in the Pearl River Delta for the aged.
