What is the theme of Jia Sheng's poem and who is the author?

1, Jia Sheng is intended to express the poet's incompetence through Jia Yi's experience. Its focus is not on personal gains and losses, but on pointing out that feudal rulers can't really attach importance to talents and make them play a role in politics.

2. Li Shangyin, the author of Jia Sheng in the Tang Dynasty, full text: Seeking the virtuous to visit courtiers, Jia Sheng is even more incoherent. Poor midnight is unprecedented, and Mo Wen people ask ghosts and gods.

3. Translation: Emperor Wen of Han invited the sages to summon the relegated courtiers in the front hall of Weiyang Palace. Jia Yi's talent is unparalleled. Unfortunately, Emperor Wendi moved his knee to Jia Yi's classroom in the middle of the night, not asking about the people's vitality, but only about ghosts and gods.
