See Mencius Hui Liang Wang's "Cultivating the Meaning of Heaven and Earth": "I am good at cultivating my noble spirit" and "noble spirit is the meaning of heaven and earth". Righteousness originally refers to a way of keeping in good health. After Wen Tianxiang's Song of Benevolence and Righteousness, its connotation has been fully expanded, and the meaning of heaven and earth has been endowed with personalized connotations such as noble character, loyalty, hatred of evil, upholding justice and serving the people. The "ancient and modern perfection law" is a personal moral sentiment that advocates the pursuit of perfection and cultivates indomitable personality. Only with noble morality can we have noble personality, and only with noble personality can we have a noble life.
