Wealth can't confuse his thoughts, poverty can't change his ethics, and power can't subdue his will. Three sentences are Mencius' standard of being a man: wealth is admired, poverty is hated, and power is feared, but you can't be moved by it, which shows a person's noble character of adhering to integrity and righteousness. This neatly arranged sentence is magnificent and powerful. Later, these three sentences became famous sayings of determination and discipline, and became the motto of many heroes and people with lofty ideals.
