During the Jin Dynasty, Le Guang was known for his philosophical discussions but was not skilled at writing. As he was about to depart from his official post, he requested Pan Yue to compose a memorial for him. Pan Yue responded, If I were to capture your essence, I would certainly be able to.

Le Guang then verbally expressed his aspirations and thoughts in over two hundred sentences. Pan Yue organized and refined these ideas, creating a famous literary work.

Contemporaries at the time commented, If Le Guang had not lent his ideas to Pan Yues pen, and Pan Yue had not incorporated Le Guangs intent, such a masterpiece could not have been created.
