30-Second Overview: Cai Jian-an (channel name "Cai Heipi," early username "Heipi") was born in 2002. He began making videos in high school because he felt "no one was covering transportation topics," with his first work being 10 Things You Didn't Know About Taipei MRT. Twelve years later, he stood on the stage of the 26th Golden Road Awards, hailed as the "Oscars of the Transportation Industry," to receive the Special Contribution Award. The core tension of this story lies in this: in early 2025, he announced a hiatus, and the channel went silent for half a year. Everyone thought he was disappearing, but his return with the "Taiwan 360" local series actually exerted a deeper force. The Wuchiu special feature topped the channel homepage, with views breaking 100,000. A boy who grew up memorizing MRT station names ultimately pointed his lens at the most forgotten corners on the map. This article is not about the rise of an internet celebrity, but about how a creator found the reason why he had to keep going amidst the contradiction of "no one watches when I post, but people wait when I stop."
Why Read About This Person
In Taiwan's YouTube knowledge ecosystem, there are a few numbers worth pausing to look at. One is "100": Cai Jian-an spent about six years accumulating 100 transportation infrastructure videos, each painstakingly extracted page by page from government project proposals, engineering records, and historical/geographical data. The production cycle of this content is in a completely different time unit than an unboxing video or a mukbang. Another is "0": From January to October 2025, he went nine months without updating. In the logic of algorithms, a channel with no new content for nine months is almost equivalent to a death sentence. The third is "30": After his return, his first local special focused on Wuchiu, a place with a total population of only about thirty people1. One hundred videos, nine months, thirty people—these three numbers are exactly the three keys to understanding this creator: how he makes videos, why he stopped, and why he came back.
There is also a quieter number hidden behind: As of December 2025, his channel had 189 videos, 56.61 million total views, and 260,000 subscribers2. By July 2026, his videos were included in high school geography textbooks3. From YouTube to textbooks, he walked this path for thirteen years. This article will walk back along this path: first returning to the little boy asking in the MRT station, "Where will this route lead?" and then looking at how he spent twelve years turning this question into a whole Taiwan transportation knowledge base.
The Boy Who Memorized Station Names
Cai Jian-an was born on May 28, 20024. His childhood was like many other Taiwanese children, nothing special—except for the way he traveled. Other children looked at their phones on the MRT or chatted with classmates; he looked out the window. In later interviews, he described the starting point of this habit: As a child, he was a boy who loved taking rides and the MRT, liked looking at the scenery outside the window and imagining the world, and would also be curious inside the MRT stations, "How big is this station exactly? And where does this route lead?"5
This curiosity turned into a skill bordering on the特异 (special/unique): He could memorize every station name6. If you have ever ridden with a rail fan, you know how rare this is among Taiwanese kids. Most people memorize video game weapon codes; he memorized every station on the Wenhu Line from Nangang Exhibition Center to Taipei Zoo.

His creative career did not start with transportation. In 2013, at age eleven, he opened his YouTube channel. His early identity was that of a Minecraft map creator, making small game maps like "Escape from Taiwan Junior High" and "Escape from Movie City Department Store," gaining over 10,000 to 100,000 views in the player community4. During the same period, the channel also produced knowledge, live-stream, and entertainment videos. By 2016, the channel had accumulated only 10,000 views; by 2018, subscribers were 2,500, with total views at 250,0004. In today's self-media context, these numbers mean nothing happened.
What truly changed the trajectory was high school. He stated the reason for the shift himself when receiving the Golden Road Award: "In high school, I felt no one was doing transportation topics, and I felt I knew more than my peers, so I started making videos. The theme of the first video was 10 Taipei MRT Trivia."6 Reports from the National Educational Broadcasting (NEB) provided more specific coordinates: this debut transportation video was born in 20207. The route then started from railways and MRT, extending all the way to highways, Taiwan geography, and history. Most of the data was searched by himself, and he consulted industry professionals when writing scripts6.
📝 Curator's Note: Note the timing of this transformation. Around 2019–2020, Taiwan's YouTube was filled with unboxings, challenges, and mukbangs; knowledge-based transportation content was a true blank space. He chose not a hot track, but a stop sign no one stood at—just like his favorite saying later: On this route, no one has planned the terminal station yet.
"Railway Bar" and 100 Videos
"Railway Bar" is his most famous series, broadcast steadily starting in 2020. Representative works include National Highway 6 Piercing the Central Mountain Range Directly to Hualien? (over 3.1 million views), as well as 1.7 million views for the Xueshan Tunnel, 1.6 million views for Taiwan's Most Useless High-Speed Rail Station: Tainan Station, and 1.8 million views for the Taoyuan Airport MRT8.
Along National Highway 6, the Central Mountain Range is shrouded in clouds and mist. Cai Heipi's first video to break 3 million views is about this highway that has been under construction for so long but still hasn't reached Hualien. Photo: OnionBulb, 2022-03-26, CC BY-SA 4.0

These numbers are top-tier among Taiwan's knowledge creators, but what is more worth looking at is the orientation of topic selection: His popular videos are almost all "infrastructure Taiwan almost built, but didn't": National Highway 6 piercing the mountain range, National Highway 9 building from Changhua to Kaohsiung, and a highway plan exceeding 3,500 kilometers8. In other words, what he sells best is the "unfinished" in Taiwan's transportation history.
Another category of topic selection is "built after a long wait": The Taoyuan Airport MRT took twenty-four years from planning to opening, making it one of the longest construction periods for rail infrastructure in Taiwan's MRT history. He used 1.8 million views to retell this "waited for two generations" route to the younger generation. This is the most unique layer in his content: The timeline of transportation infrastructure is placed side by side with the memory history of Taiwanese society. After watching, viewers often see not just engineering, but a public history of "why did we wait so long."
The rail fan community gave him a precise ecological niche: Some viewers described it as "his early themes were almost all content you couldn't find on Wikipedia, adding quite a bit of stuff only found in project proposals"9. And by the end of 2025, statistical figures laid bare the scale of this niche: 189 videos, 56.61 million total views, averaging 300,000 views per video—this is several orders of magnitude higher than single reports from most small-to-medium Taiwanese media2. In May 2021, the Taiwan Transportation Association's "Transportation Society Lecture" invited him to give a speech, introducing him as "Transportation Video Expert Cai Jian-an (Heipi)"10. A nineteen-year-old student was called an expert by Taiwan's most senior transportation society.
In the two years after his return, the channel's map expanded significantly. Beyond "Railway Bar" centered on railways and MRT, and "Transportation Bar" centered on highways, he successively pushed "Taiwan 360" from offshore islands to counties and cities across the island, and launched a pure history series called "Heipi Talks About Old Cities," narrating a city's history in the style of old cities, with over twenty videos so far8. Recent works include the continuing fermentation of the Wuchiu sequel Map Erased "Townships"? (101,000 views), Did Taiwan Almost Have National Highway 32? Over 3,500 km Highway Plan (118,000 views), and Sanxing Line Opening Unboxing (87,000 views)8. Topic selection still maintains the two extremes of "unfinished" and "most remote."
He also began pushing this Taiwan narrative into the English-speaking world. In mid-2025, the channel launched the English version of Introduction to Taiwan: The Formosa You've Never Discovered, opening with the ancient name "Formosa" to introduce the face of Taiwan ignored by most international audiences, with about 150,000 views—for an English video on purely Taiwan-local topics, this number represents that his narrative framework holds up outside the Chinese-speaking circle8. A creator who started by memorizing Taipei MRT station names is now translating "Taiwan's story" into a version the world can read.
But a creator's daily life has no award stage. He wrote this passage on IG himself: "Many people know me because of MRT, highways, and railways, and often directly call me a 'Transportation YouTuber'; but for me, what I have always been fascinated by is never the transportation vehicles themselves. What I want to know is, why was this highway built here?"11
His production process was fully recorded in an interview by the National Educational Broadcasting (NEB) at the end of 2025: After collecting data and finishing the script, "I always ask these experts to help review, improving accuracy"7. One person handles data search, map making, scripts, and editing9, layered with professional把关 (gatekeeping). This is the prototype of the Golden Road Award's reason for the award: The Ministry of Transportation and Communications' Railways Administration thanked him for "introducing major government transportation infrastructure in a relaxed, easy-to-understand way, bridging the distance between the public sector and the people, and also opening an opportunity for mutual understanding among all parties during the dark period of transportation infrastructure"6.
Hiatus, Then Disappearance
In January 2025, Cai Jian-an announced a hiatus on his channel12.
For a knowledge channel, hiatus is another name for the death penalty. Taiwanese creators in the transportation geography niche persisting is already extremely difficult; peers in the same circle like "Railway Office" and "Penguin Transportation Notes" also went offline or fell into a low tide successively9. During that half-year, the most common comments on social media were "Knowledge YT Great Collapse?" and "What was he doing for disappearing for half a year?"12.
He didn't explain for long. In October 2025, on the twelfth anniversary of the channel's founding, he returned, bringing a whole set of restart plans: New name "Cai Heipi" (the original "Heipi" had too high overlap, making searches prone to collisions with others), new email, new channel positioning, channel membership, LINE stickers, and a brand new series: "Taiwan 360 Taiwan 360," aiming to tell the historical and geographical knowledge of every township, county, and island in Taiwan one by one12. He did not disappear during the hiatus. The timeline of the hiatus video Knowledge YT Great Collapse? Cai Heipi Disappearing for Half a Year Actually Doing This... honestly displayed his life: School courses, editing classes, Korean classes, and channel projects collaborating with classmates. It turned out these nine months, he used "rest" to reorganize the creative system13.
Behind the name change is the maturity of a creator's identity: "Heipi" is a nickname commonly used in the gaming circle, with high overlap; "Cai Heipi" locks the given name and nickname together, making collisions in search almost impossible. He later changed his self-introduction on social platforms to "I am Cai Heipi!". From "a nickname" to "a name," this step took him twelve years.
The topic selection of this restart forms a subtle echo with the little boy from twelve years ago. Twelve years ago, he stood in the MRT station asking "Where will this route lead?"; twelve years later, he pointed the lens at the most marginal island on the Taiwan map—Wuchiu.
Forgotten Territory: Wuchiu and the Marine Perspective

The Mysterious Forbidden Zone of Kinmen Central: Wuchiu topped the channel homepage, with views exceeding 100,0008. Wuchiu is the most remote township in Kinmen County, with a population remaining of only about thirty people. Going home requires jumping on a boat, and one cannot go out after dark. This "island among islands" has almost disappeared from the map cognition of general Taiwanese people1. He later continuously pushed "Taiwan 360" further: Unlocking all of Taiwan's hundreds of offshore islands, the southernmost and northernmost spanning 1,800 kilometers8.
The completion of the Wuchiu special was also a report card for his formal training. Cai Jian-an was then a student in the "Broadcasting and Sound Design Group" of the Department of Broadcasting and Television, Shih Chien University2. He collaborated with a broadcasting department classmate, Yang Yao-ai, to produce the program Forgotten Territory, exploring Wuchiu's history and cultural preservation, winning the 22nd Golden Sound Award for Social Care Program hosted by the National Educational Broadcasting2. And as early as the channel's tenth anniversary, his video Taoyuan Zhongli, One Country Two Systems? Why Do Zhongli People Hate Taoyuan So Much! The Dispute Between Two Cities Has Lasted for a Century!? won the 5th Zouzhong Award "Golden Brain Award"2. From Zouzhong Award to Golden Sound Award to Golden Road Award, the three trophies of Taiwan's digital content circle fell into the hands of the same 23-year-old creator successively.
In his Golden Road Award acceptance speech, he added another important footnote: The award day, December 12, 2025, happened to be the 12th anniversary of his channel's founding: "To receive such a meaningful award on this day is a very wondrous fate for me"14. In the same video, he also revealed a little-known promotion history: In the early stages of Taiwan's light rail construction, society generally did not understand it, and he worked with Kaohsiung City to do serious public promotion. "The image that floated up in my mind was an old lady holding a child's hand, riding the bus in Kaohsiung's green tunnel. That image was very warm and very moving"14. He also mentioned that his greatest pride as a knowledge disseminator was not views, but that "many viewers, because of my videos, decided to study transportation, urban planning, geography-related majors, and even enter the public sector"14. A YouTuber's influence is extending from the screen into classrooms and the civil service system.
In the Golden Road Award interview, he spoke the deepest foundation of his ten years of creation: "From the perspective of the continental empire, Taiwan is on the periphery; but from the marine perspective, Taiwan is the navigator of the ocean; therefore, we must cherish this land of Taiwan well, and stop to listen to the stories of this land."6
This sentence is worth pausing to listen to. A creator making transportation infrastructure videos ultimately arrived at the intersection of geopolitics and national identity: Transportation infrastructure is never just engineering; it is a question of "whether this land deserves to be treated well." In the Railways Administration's comment for him, there is a sentence easily overlooked: "Opening an opportunity for mutual understanding among all parties during the dark period of transportation infrastructure"6. His videos allowed the general public to understand why a highway would cost hundreds of billions and take decades to build7, thus removing a layer of "you don't understand" wall between the public sector and the people.
✦ "Because you never know what kind of people you will meet, or what wonderful scenery you will see, after taking the first step." — Cai Jian-an5
Controversies Were Not Hidden
This article does not intend to write him as a perfect character. The rail fan community has clear criticisms of him: Some pointed out his "abnormal obsession" with Xizhi's transportation planning, suspecting he lives in Xizhi9; others dug up his pre-hiatus controversial videos—two "fantasy route" proposals questioned for feasibility, which he later took down (Daxike Station, Zhonghe Cross-Island Line). Some viewers bluntly said "he then spoke of fantasy routes as if they would definitely be built"9.
His way of responding to criticism was also recorded in the award interview: "I am very grateful for some critical comments, which let me know how I can be better,审视 (examine) the shortcomings, and progress further."6
📝 Curator's Note: Here is a standard sample of creator growth. Taking down problematic videos, admitting shortcomings, turning criticism into motivation for revision—then responding with the Golden Road Award two years later and deeper topic selection (Wuchiu, Taiwan 360). The most valuable credit in the traffic era is not "never making mistakes," but "how to handle it when you make mistakes."
After 260,000 Subscribers
As of December 2025, his channel had a total of 189 videos, 56.61 million total views, and over 260,000 subscribers2. The channel number shows 265K and is continuing to grow8. His videos were even included in high school geography textbooks. The publisher sent him the book, and he posted on July 2026: "After flipping it open, I saw my own video inside; at that moment, the feeling was very wondrous."15 He also called himself "I am Cai Heipi!" in the post, introducing this new identity in the first tone3. In February 2026, for the "Railway Bar" sixth anniversary, he announced the restart of the entire railway and transportation series16, and in the award acceptance speech video, he "called out" to the Minister of Transportation and Communications and various bureaus: "If there are projects in the future that you hope more people will see... like the Third Terminal or the Daxian Bridge, if you have any cases you want to collaborate with me on, please feel free to contact me! I would be very happy to unbox them for you~"14. Behind the half-joking tone is his serious declaration of self-expectation to be a "bridge between the public sector and the private sector"14. From entering university in 2020 to 2026, he studied in the Broadcasting and Television Department of Shih Chien University for a full seven years17.
This bridge, his call-out was timely. Daxian Bridge opened to traffic on May 12, 2026.

If using one bridge to summarize the character of Taiwan's transportation engineering, Daxian Bridge might be the best example: Proposed for construction in 1980, included in the "Six-Year National Development" in 1992, won the international design competition by the team of the late master architect Zaha Hadid in 2015—the "Quiet Dancer"流线 (streamlined) shape was her last architectural design work before her death18. The main bridge from 2017 to 2018 failed to bid seven times consecutively due to the high technical threshold of the bridge type, stopping construction for over two years; it officially started construction in 2019; closed in September 2025, with total costs adding up to NT$23 billion18. Starting from April 2026, the Ministry of Transportation and Communications' Highway Bureau held opening series activities (road running, cycling, starry sky concerts, bridge picnics), allowing people to walk onto the bridge before opening19, officially opening on May 12, shortening the driving distance between Danshui and Bali by 15 kilometers, saving about 25 minutes during peak hours19. The world's longest single-tower asymmetric cable-stayed bridge (main span 450 meters), design life 120 years18. This is exactly the kind of infrastructure Cai Heipi's lens loves most: Fermenting for half a century, a public project worthy of complete recording. When he called out to "unbox for you," this bridge was just in the opening season; and he, like every bridge he has filmed, stands between the history of the bridge and the curiosity of the people.
In May 2026, he welcomed another milestone: Graduation. He posted on IG: "From entering university in 2020 to 2026, I studied for a full 7 years of college (Am I studying Medicine XD?) This long journey is finally arriving at the terminal station, I am ready to graduate!!"20 Hidden in the same post is a story very representative of him: He never took a photo with his 100,000 subscriber plaque: "After receiving the plaque, I immediately put it deep in my room, then walked to the computer to continue editing," until seven years later, he "thanked AI's help, allowing me to have the first photo with this plaque"20. In mid-May, he held a graduation exhibition at the Songshan Cultural and Creative Park, hand-drawing limited postcards to give to visiting audiences, and also confessed "Administrative processes are all handled by me alone; relying on my own ability, I really couldn't hold a formal meet-and-greet"20. One person handling everything, from scripts to administration, this is the underlying truth of Cai Heipi's channel.20
It is worth mentioning the channel's operation model. When he returned in October 2025, he simultaneously launched the channel membership system "Team Tsai," putting behind-the-scenes footage and bloopers into membership-exclusive content, including bloopers from the Golden Sound Award-winning Forgotten Territory—the award-winning video itself was also revealed first from the membership zone12. This "public content builds trust, membership content deepens connection" dual-track structure is his realistic choice to maintain the channel under the limit of a one-person team: Not relying on massive updates to fight algorithms, but relying on the depth of each video to exchange for the audience's long-term trust and membership conversion.

From a boy memorizing MRT station names, to a 23-year-old creator standing on the stage of the "Oscars of the Transportation Industry," to the "textbook-level" influence of videos being written into high school geography textbooks, Cai Jian-an's story leaves a very specific demonstration for Taiwan's digital creation circle: Deep topic selection will not die in the algorithm; it just needs a longer compound interest period. He said a sentence on the day of the award that seemed like a summary: "One of my wishes since childhood was to become a knowledge enlightener who could lead everyone to see this world. I didn't expect to realize this wish in my twenties."5
Next time you ride the MRT, you might as well look at the station name signs. For Cai Heipi, those are not just station name signs—those are the starting point of his entire creative career.
