Xiao Yuehan Kehan: The Historian Who Built a Universe Out of Tongliao and Taught Millions to See the World from Below

Xiao Yuehan Kehan, whose real name is simply Xiao Yuehan, is a Chinese history content creator and one of the most influential figures in Bilibili's knowledge section. He is a native of Tongliao, a city in Inner Mongolia, and he operates his channel as a solo creator, a fact that is all the more remarkable given the scale of his reach. As of March 2026, his Bilibili channel has over 10.62 million followers, making him the first creator in Bilibili's knowledge category to surpass the ten-million mark. Before becoming a video creator, he was an active answerer on Zhihu, the Chinese question-and-answer platform, where he wrote extensively on Soviet history, military affairs, and international politics under the name "Little John," a reference to the operational codename of Frank Underwood in the American television series *House of Cards*. His Zhihu answers accumulated a substantial following, and when he began uploading videos to Bilibili in November 2020, his early content consisted largely of curated selections from those written answers. His breakthrough was immediate: his first major video, "Why Was the Soviet Union So Powerful?", released on November 14, 2020, has accumulated over 33.9 million views as of August 2025, a figure that remains one of the highest in Bilibili's knowledge category.

What distinguishes Xiao Yuehan Kehan from the crowded field of Chinese history educators is his construction of an entire narrative and linguistic universe around a set of recurring themes and a highly distinctive lexicon. He organizes his content into several ongoing series. The "Bizarre Small Nations" series examines the histories of countries that are largely absent from mainstream historical discourse: The Gambia, Nauru, Burkina Faso, Albania, and dozens of others, each treated with the same seriousness and narrative care that larger nations typically receive. The "Hardcore Ruthless People" series abandons the traditional focus on kings, generals, and statesmen, instead telling the stories of criminals, con artists, spies, soldiers, and ordinary people whose lives intersected with the great upheavals of the nineteenth and twentieth centuries in unexpected ways. The "Bizarre Organizations" series applies the same approach to institutions, from intelligence agencies to revolutionary cells. And the "Little John" series operates as a kind of adult fairy tale, using the conventions of fantasy narrative to pose questions about human psychology and historical development. Across all these series, he maintains a commitment to what Chinese critics have described as a "people's history" perspective, a historiographical approach that prioritizes the experiences of ordinary individuals over the actions of elites and that seeks to understand historical events through the material conditions and social forces that shaped them.

The linguistic dimension of Xiao Yuehan Kehan's work is arguably as important as its historical content. He has developed a distinctive vocabulary and set of running jokes that his fans refer to collectively as the "Tongliao Universe" (通辽宇宙). The most famous of these is his use of Tongliao itself as a unit of measurement: when describing the area of a foreign country, he will often compare it to his hometown, producing statements such as "Albania is only half a Tongliao." This running gag has become so iconic that "Tongliao" (abbreviated as "T") now functions as a semi-serious unit of area measurement within his community, and the phrase "nT" is used by fans to express the size of any territory. He employs puns, dialect expressions, and colloquial idioms drawn from northeastern Chinese speech, and he has a talent for coining memorable nicknames for historical figures, such as "Soviet Cousin" for Leonid Brezhnev and "American Cousin" for Richard Nixon, that have entered the broader vocabulary of Chinese internet culture. This linguistic creativity has spawned a wave of imitation among other history creators and has been credited with fundamentally altering the style of Chinese online history communication, making it more playful, more accessible, and more attentive to the rhetorical strategies that sustain audience engagement.

The commercial and institutional recognition of Xiao Yuehan Kehan's work has been substantial and consistent. He was named to Bilibili's Top 100 UP Creators list for four consecutive years, from 2021 through 2024, and in 2022 he received the platform's "Highest Popularity" award in addition to his Top 100 designation. In January 2026, he was again recognized as one of the 2025 Top 100 UP Creators. His average video receives over three million views, and his collaboration with Xinhua News Agency in December 2021, a "Hardcore Ruthless People" episode about the British spy George Blake, was widely praised as a model for how independent creators could engage with mainstream institutions without sacrificing their distinctive voice. A commentator at the time observed that the episode demonstrated that "telling China's story does not necessarily require telling a Chinese story," a formulation that captures the universalist ambition underlying his work. In 2023, he co-authored a book titled *Heroes and the Times* with two other history writers, extending his reach from video into print media.

The broader social significance of Xiao Yuehan Kehan's project lies in his demonstration that historical knowledge can be both intellectually rigorous and genuinely popular without compromising either quality. He cites sources and includes reference lists in his videos, yet he presents his material with the pacing and narrative momentum of a serialized drama. His choice of subjects, small nations and obscure individuals rather than great powers and famous leaders, reflects a deliberate political and ethical commitment to expanding his audience's understanding of the world beyond the narrow frame that mainstream media typically provides. For young Chinese viewers, many of whom have limited exposure to the histories of the Global South or to the lived experiences of ordinary people in distant places, his videos offer an education that is both geographically and socially broadening. At the same time, his work has not been without controversy; in 2025, a video in his "Hardcore Ruthless People" series was found to contain serious factual errors, prompting him to issue a public apology and acknowledge that his content production relied on a single external researcher whose sourcing had proven unreliable. His handling of the incident, including a self-deprecating reference to "poor quality control" in a subsequent video, was received by many fans as a genuine acknowledgment of fallibility rather than a defensive deflection, and it arguably strengthened rather than damaged his credibility by demonstrating that he takes his audience's trust seriously.

In summary, Xiao Yuehan Kehan represents a distinctive model of the creator as a public historian, one who treats the video platform as a space for serious intellectual work while refusing to abandon the entertainment value that makes that work accessible to a mass audience. His Tongliao Universe is not merely a collection of running jokes but a coherent rhetorical system that binds together his diverse subject matter and creates a sense of shared community among his viewers. His commitment to a people's history perspective gives his work an ethical orientation that distinguishes it from both conventional academic history and the personality-driven content that dominates much of the platform. And his willingness to acknowledge error and to continue producing work in the face of criticism suggests a maturity that is rare in the often volatile ecosystem of online knowledge production. For Bilibili, he is a cornerstone of the platform's knowledge section and a demonstration that independent creators can achieve both popularity and intellectual seriousness. For viewers around the world, he offers a model of historical storytelling that is rooted in a specific place, Tongliao, but speaks to a universal curiosity about how ordinary people have lived, struggled, and survived in a world shaped by forces far larger than themselves.
