But at that time, he was just a small official who served as a warrior knight under Emperor Wu of the Han Dynasty, so Sima Xiangru felt that he had never met a bosom friend.

Later, during the period of Emperor Wu of the Han Dynasty, I read his Zi Xufu and greatly appreciated it. At this time, a man named Yang Deyi around Emperor Wu recommended Sima Xiangru, and Emperor Wu immediately called Sima Xiangru to Beijing. Sima Xiangru told Emperor Wu of the Han Dynasty that Zi Xufu was nothing, so he made the famous "Shang Lin Fu".
