To better understand and consistently improve the public welfare, happiness and wealth have been discussed in the academia for ages, which deserves the researchers’ attention to reiterate such relationship when it comes to the case of China. This paper endeavors to briefly review what happiness and wealth are respectively, in what ways they can be measured, and describe the relationship between them. Then, the paper mainly uses second data analysis based on the survey of World Values Survey and National Bureau of Statistics of China to introduce the analytic foundation of this paper, which are key indicators that make up wealth like income, the status of a family's main source of income, expectations of future salary level, etc. and propose the meanings of subjective happiness. Besides, we also discussed the influence of these components of wealth on happiness, vice versa. During the process of research, we discover that although with the increase of wealth, the urgency of survival in China has significantly decreased, and people's happiness has also been on the rise. However, when wealth is no longer the main factor affecting Chinese, other factors such as educational level, and the gap between urban and rural areas have a very unignorable impact on happiness of Chinese people. Therefore, at the end of the paper, conclusions can be drawn upon the positive relevance between wealth and happiness. Whereas, their relationship is a complex and nuanced subject required of more thoughtful observation, and what lies ahead is the focus of extensive research in the fields of psychology, economics, and sociology to give a full picture of this relationship, for example, the negative impact of wealth on happiness in the long run.
