One of the important aspects of Confucianism is to pay attention to 'learning'. In Confucianism, the process of learning can not be separated from that of adulthood: Xunzi inherited this idea. Xunzi believed that 'learning' itself should aim at 'adults' and become 'saints'. 'Learning' is a process of continuous accumulation. Xunzi advocates the theory of evil nature. Therefore, only by giving full play to the initiative of 'heart' to learn the sacred king's etiquette and righteousness and turn nature into falsehood can it lead to 'adulthood'. Xunzi's thinking about 'adults' embodies a moral ideal of personality, and 'learning' also points to the study of ethics and morality. From this we can see that 'learning' is inevitable for 'adults', but because people are always unable to 'complete' people, so 'learning' is also an endless process, meaning 'learning as adults'. Man is always in the process of transcending himself and realizing himself.
