📖 Meaning
A metaphor for someone who is ignorant yet arrogantly conceited, believing themselves superior despite limited knowledge or experience. It describes a person who overestimates their own importance while being unaware of how little they truly know.
📜 Origin Story
During the Han Dynasty, the King of Yelang, a tiny kingdom in southwestern China, asked an envoy from the Han Empire, 'Which is larger, Han or Yelang?' The King of Dian had asked the same question earlier. Both rulers were isolated by poor roads and had never ventured beyond their own territories, so they had no conception of the vastness of the Han Empire. This story is recorded in Sima Qian's 'Records of the Grand Historian' (《史记·西南夷列传》). The idiom has since been used to mock those who are parochial and self-important.
💡 Example Usage
他才学了几天就夜郎自大，以为自己什么都懂了。
