In times of war, many children were starving and homeless.
Tips
history
嗷嗷 mimics a baby bird's pitiful cry — the image comes from 《诗经·小雅·鸿雁》: 鸿雁于飞,哀鸣嗷嗷, 'wild geese in flight, mournfully crying.' Han historian Xun Yue (荀悦) later applied it to starving people.
memory
嗷嗷 (áo'áo) is onomatopoeia — picture the open beaks of baby birds in a nest. 哺 (bǔ) means 'to feed,' as in 哺乳 (breastfeed).
