"In the画面 of the Korean drama, the person sitting in front is Emperor Yang of Sui from the drama. Look at the screen behind him, and there is even a signature of Chairman Mao!" A netizen exclaimed in surprise about an inconceivable "time-travel" scene in the TV series "Yuan Gaosuwen" aired on South Korea's SBS channel, in a post titled "Korean Drama Blunder: Chairman Mao's Poems Appear in Sui Dynasty".
In the screenshot of the drama, the author can clearly see that Emperor Yang Guang of Sui is seated on the dragon throne, and behind him on the screen is precisely the poem "Qinyuan Spring • Snow", which was published in the 1940s and personally written by Mao Zedong. Moreover, even if the poems were not written by Chairman Mao, the flourishing of Tang poetry and Song lyrics, these two great treasures of Chinese culture, also appeared behind Emperor Yang of Sui.
