In recent years，the report of the World Health Organization and the United Nations that the average life expectancy of Hong Kong residents ranked first in the world for several consecutive years has attracted the attention of all walks of life at home and abroad. Relevant studies have analyzed various reasons for the longest life expectancy of Hong Kong residents from the perspectives of environment，transportation，health care，clothing，food，housing and transportation，and their research results have also been recognized by the academic community and the public. So far，the studies on the long life expectancy in Hong Kong are mostly based on the analysis of quantifiable external factors，while the analysis of internal factors in the humanities and social sciences is less.
