◎ Vernacular explanation: Mencius said, "If a person has no sympathy for pain, he can't be regarded as a person; Without shame and hatred, you can't be a person; A heart without humility and courtesy cannot be regarded as a person; Without the heart of right and wrong, good and evil, you can't be regarded as a person; Compassion for pain is the beginning of kindness; A heart of shame and hatred is the beginning of justice; Modesty is the beginning of courtesy, and the heart of distinguishing right from wrong, good and evil is the beginning of wisdom; A man has four ends of benevolence, righteousness, propriety and wisdom, just as he has four limbs. 」
