Taking the Chongxi period as the background, it tells the story of the emperor Zheng Yun and the grassland representative Hulan struggling with power, national integration and personal emotions in the tide of the times.
After Zheng Yun ascended the throne, he devoted himself to breaking down ethnic barriers and promoting "universal unity". He promoted Agula, a young man from the grassland, and supported Heguangtang, a place where students of all ethnic groups coexist, in an attempt to eliminate past hatred and suspicion. Hulan, who comes from the north with the magnanimity and wisdom of the grassland, is not only a witness to this process, but also develops a special relationship with Zheng Yun that transcends identity and ethnicity through mutual understanding.
However, the undercurrent of the court and the interests of the tribe are like invisible shackles, so that the two people's emotions are always controlled by the country and the country. From the joy of autumn to the impact of secrets, from the consensus of returning to the alienation caused by the weighing of reality, they had to bury their personal emotions deeply while protecting the land and people behind them. In the end, Zheng Yun protects the country thousands of miles away with the responsibility of an emperor, and Hulan takes root in the grasslands with the responsibility of a tribe. Across the world from home and country, the two turn their unspoken feelings into a common insistence on "the world is one". In the wind and snow of the times, each of them reaches their destined ending, leaving behind a melancholy past about responsibility, sacrifice and distant hope.
