In the Sui Dynasty, there was a man named Shimi. The owner of the word method, a native of Chang 'an, Jingzhao, was originally from Xiangping, Liaodong (now the south of Liaoyang, Liaoning), and his ancestors were nobles of the Northern Zhou Dynasty and the Sui Dynasty. By his generation, it had declined.

Under the protection of grandfathers, Shi Mi got a Wu Zhi at the age of 15 and served as a bodyguard in the court of Yang Di.

One day, Emperor Yang Di saw him at the guard. After returning to the palace, he asked Yuwen Shu, the general of the left guard, "Who was the black face in the left guard just now?"

Yuwen Shu replied: "He is the son of the late Pu Shan Gong Li Kuan, and his name is Li Mi."

Emperor Yang Di said, "This child looks very unusual. Don't let him be a bodyguard in the palace. "

Later, Yuwen Shu said to Shi Mi, "My good brother is so talented that he should get an official position on the basis of talent. The palace guard is a trivial job, not a place to train talents. "

Shimi was very happy, so she resigned due to illness and concentrated on her studies. Because she lives by herding cows, she often sits on the back of cows and studies.

One day, Shi Biao heard that there lived a well-read man named Bao Kai on Goushan Mountain, so he went to learn from him. Shi Biao set off on a cow with a thin straw mat on its back and a copy of Hanshu hanging on its corner. Shi Mi is reading Hanshu on the way. It happened that Su Yang, the King of Yue at that time, rode behind Shimi. Seeing the young man working so hard, he stopped his horse and praised him: "Where did this scholar work so hard?"

When Shi Biao was an official in the palace, he saw the King of Yue, so he quickly jumped down from the cow's back to visit. Su Yang asked what Shi Mi was reading, and Shi Mi told him that he was reading Hanshu.

Su Yang and Shi Mi chatted for a while and found that Shi Mi had an unusual conversation. After returning home, Su Yang said to his son Yang Xuangan, "I think Shimi's academic ability is better than your brother's. You can associate with him. " Later, Yang Xuangan really came to make friends with Shi Biao, and they became good friends.

However, Li Mi left a beautiful talk of studying hard because of "hanging books in the corner". Together with stories such as "Digging the wall to get light" and "Firefly reflecting snow", it has become the idiom allusion of "Starfly and Sun Kang reflecting snow" in the Four Seasons Reading Song.
