During the Sui Dynasty, Li Mi was assigned as a guard in the palace of Emperor Yang of Sui when he was young. Clever and lively by nature, he often looked around while on duty. Emperor Yang considered him insufficiently steady and eventually dismissed him from the position.
However, Li Mi did not become discouraged. After returning home, he devoted himself even more diligently to studying and resolved to become a knowledgeable person. On one occasion, while riding an ox to visit a friend, he hung a copy of the Book of Han on the ox’s horn and continued reading along the journey. Since then, the story of “reading with a book hanging from an ox horn” has been passed down as a famous tale of diligence in study.
隋朝时期的李密，少年时曾被派到隋炀帝宫中担任侍卫。他生性机灵活泼，在值班时常常左顾右盼，因此被隋炀帝认为不够稳重，最终被免去了差事。
