6. What is filial piety? Filial piety is the sun, bringing warmth to people; Filial piety is a mountain, which brings people dependence; Filial piety is a gem and wealth. Filial piety is the traditional virtue of the Chinese nation, and it is a business card that we stand in the east of the world. The long-standing proverb "All virtues and filial piety come first" is still praised by people today. As Mencius said, "no father, no king and no beast" fully illustrates the importance of filial piety.
