In the deep palace of the late Tang Dynasty, the foreign princess Yu Ludai was like a bird trapped in a golden cage, looking at her homeland in the distance within the oppressive palace walls. Gu Qingzhou, the Hanlin painter who was ordered to paint her portrait, captured the sadness in her eyes and the uniqueness of her soul with pen and ink, and the two became close friends under the strict palace regulations. When Yuludai's motherland fell, she became a political victim, and a secret decree was issued to bury her. Gu Qingzhou risked his life to rescue him, but ended up trapped in a tight siege. In order to protect his beloved, Yu Ludai drank the poison with a smile, leaving behind a farewell message of "May your life be as long as your pen and ink remain clear". Gu Qingzhou was exiled to Lingnan. For the rest of his life, he could only paint his beauty's face repeatedly with paintings, integrating his endless thoughts and remorse into his pen and ink until the end of his life. The jade shattered the palace wall, and the painting carried the soul. This deep feeling that cannot be tolerated in the world has finally become a poignant and beautiful song, shining brightly in the dust of history.
