Both Mencius and Xunzi's educational thoughts have their unique contributions and values, and it is difficult to simply judge which is more advanced. There are obvious differences between them in human nature theory and teaching thought, and these differences also reflect their different educational views.

Mencius firmly believed that human nature is good and that the function of education lies in developing nature. Mencius carried forward the good side, cultivated the noble spirit and achieved the ideal personality of a gentleman by means of "keeping the will and nourishing the spirit", "concentrating on nourishing the spirit" and "enjoying learning". He advocates that teaching should pay attention to internal development and emphasize the role of "thinking", and thinks that learning or teaching is a process of "preservation", "introspection" and "complacency".

Xunzi, on the other hand, advocated inherent vice that the function of education is to change the nature, and through "turning nature into falsehood", that is, the influence of education and the guidance of etiquette, the nature of evil is constantly changing and developing in the direction of goodness. He pays more attention to the influence of external factors on learning, thinks that teaching should be centered on foreign students, attaches importance to the process of "learning", and regards learning as a complete system of "listening, watching, knowing and doing". Xunzi also proposed to pay attention to the process of "accumulation" and "gradual progress", that is, both internal accumulation and external influence will change human nature.

Both Mencius and Xunzi attached great importance to the role of education. They all think that education plays an important role in people's growth and development, and can change people's nature and realize people's self-improvement and social progress through education.

To sum up, the educational thoughts of Mencius and Xunzi have their unique values and contributions, and it is difficult to simply judge which one is more advanced. In educational practice, we should flexibly use different educational methods according to specific conditions, pay attention to the role of education, and promote people's all-round development and social progress.
