Create a 9:16 mobile social media feed UI titled "Song Dynasty People's Moments" / "SONG DYNASTY SOCIAL MEDIA FEED". Blend ancient Song Dynasty culture with modern social-media humor in a time-travel interface design. The screen should simulate a smartphone social feed, but every content detail belongs to the Song Dynasty. Use a dark-mode mobile UI paired with elegant Song-style colors, subtle scholar-pattern decorations, and interface icons redesigned with Song Dynasty ornamental motifs. The avatar is a Song literati portrait. The username is "Su Dongpo SuShi_Official". The post text says that he has just arrived in Huangzhou after demotion, his mood is still okay, and he made Dongpo pork today with an attached recipe. The attached image is a close-up of Dongpo pork painted in refined gongbi style. Include a likes list mentioning Huang Tingjian, Qin Guan, Fo Yin, and about 126 people, plus comment snippets such as Wang Anshi saying "hehe" and Sima Guang saying it still tastes the same. The status bar should parody a historical network carrier, showing "Great Song Mobile 5G" and "Third Year of Yuanfeng". Make the result witty, historically flavored, readable, polished, and clearly a fictional social-media parody. Avoid real modern app logos, real platform branding, copied social-network UI marks, offensive historical caricature, unreadable text, or broken interface layout. Output aspect ratio: 9:16.
