中国大陆短视频平台近期出现"唐朝从未存在"的言论，这些内容套用西方历史阴谋论"幻影时间假说"，声称公元614年至911年间的297年历史被捏造[1]。根据这类言论，汉代之后历史直接跳跃到宋朝，李白、杜甫等人物原本属于宋代，而大唐盛世的持续时间则被改写为289年[1]。
港媒指出，此现象源于短视频平台的流量逻辑驱动[1]。在平台算法机制下，认真的历史科普内容难以获得广泛关注，反而那些违背常识、制造猎奇效果的"标题党"更容易吸引眼球，激励创作者为收割流量而制造谣言[1]。更为严重的是，这些伪史内容正源源不断输入AI训练数据库，由于人工智能缺乏独立判断史实真假的能力，仅会根据网络信息出现频率进行统计，最终形成难以修正的虚假信息循环[1]。
Short video creators on mainland Chinese platforms have recently promoted claims that the Tang Dynasty never existed, drawing on a Western historical conspiracy theory known as the "Phantom Time Hypothesis."[1] According to this false narrative, 297 years of history between 614 and 911 CE were entirely fabricated, with Chinese history supposedly jumping directly from the Han Dynasty to the Song Dynasty.[1] The theory further asserts that historical figures like poets Li Bai and Du Fu were actually Song Dynasty individuals.[1]
Hong Kong media outlets have identified this phenomenon as a consequence of short video platforms' traffic-driven algorithms, which incentivize creators to generate sensational and counter-intuitive content to attract views.[1] The platform's logic means that serious historical education receives minimal engagement, while clickbait content contradicting established facts captures attention effectively.[1] More troublingly, these false historical narratives are being fed into artificial intelligence training datasets, creating a self-reinforcing cycle of misinformation that is difficult to correct.[1] Since AI systems lack independent capacity to verify historical accuracy and instead operate by aggregating patterns based on the frequency of information appearing online, they perpetuate these fabricated accounts without critical evaluation.[1]
