A sovereign should take cherishing the people as his duty.
Tips
history
Classical term for 'the people'. The famous line 天生烝民,有物有则 ('Heaven produced the people; every thing has its rule') comes from the 《诗经·大雅·烝民》 — a poem in the Book of Songs, China's oldest poetry collection (c. 11th–7th century BCE). The character 烝 here is borrowed for 众 (zhòng, 'multitude').
register
Strictly classical/literary. In modern Chinese, 'the people' is 人民 (rénmín) or 百姓 (bǎixìng). You'll meet 烝民 only in quotations from classics, historical writing, or deliberately archaic prose.
