“…The higher education expansion in China has favored female students, and the gender gap has decreased over time and even reversed itself (Guo, 2021). This may be due to that females perform better in junior and upper secondary schools, and gaokao (China's National College Entrance Examination), higher education certificate is more important for females than males in the labor market, and females could receive more resources for the Chinese "one-child" policy (Wu et al, 2020). For example, using the ordinary least square model and quantile regression model to examine the data of gaokao in China, Zhang and Tsang (2015) found that the gender difference is not significant in mathematics on average, but significant at the top of the distribution, where females perform worse, and is significant in Chinese and English that females perform better, and females perform significantly better than males at the bottom of the distribution of mathematics, Chinese, and English.…”
