Of the total population of 36,000 people, roughly 90 % of residents can trace their ancestry to Kwangtung province in southeast mainland China. They are of the Hakka group of Chinese, while the remaining 10 % are made up of Chinese from Fukien province and the original aborigine groups. While popular custom has dubbed this area, "Long Life Place" statistics have also proven there might be some truth to the belief.
關西的景美境幽，居民生活其間，亦多長壽。
