Introduction Happiness is the eternal pursuit of human beings. Kim-Prieto et al. (2005) defined happiness widely, including positive life satisfaction, quality of life, and subjective evaluation of life in terms of emotion and cognition. Subjective well-being, which refers to the overall evaluation of the assessor’s quality of life according to self-set standards, is considered an important comprehensive psychological index to measure individuals’ quality of life (Diener, 1984).
