30-Second Overview: Teacher Black Cat is a Taiwanese social media creator, historical storyteller, and author. Starting from a Facebook fan page left behind by an overheating graphics card, he has navigated through cats and memes, WWII history primers, History is War, Facebook live streams, podcasts, and the Black Cat Creative Newsletter. He did not become famous by choosing the right platform from the start; rather, in 2015 the fan page was accidentally retained, in 2016 historical articles propelled him to more readers, in 2020 dry eye syndrome forced him to leave live streaming, and in 2024 he compiled years of experience for creators. This is not a straight line from traffic to success, but a story of a creator who, amidst shifting platforms, bodies, and income, continued to explain complex materials in ways that people were willing to understand. 1 2 3 4 5
In the summer of 2015, Teacher Black Cat was merely a player who wanted to learn how to play League of Legends like a professional. He set up a Twitch account, installed streaming software, and named his Facebook fan page. But when he first went live, the graphics card overheated and crashed before the game stream could even begin. The game stream never started, but that fan page remained. 1
Years later, this failed gaming channel evolved into a social media brand that posts photos of the black cat named Lius, narrates history, deconstructs internet traffic, and lays bare the struggles of creators on the table. Teacher Black Cat’s story is not about "how one person seized traffic"; it is closer to this: how one person, after every platform shift, redecides what they want to offer their audience.
A Fan Page That Never Successfully Launched Learned to Wait First
In his own retrospective, Teacher Black Cat said that this name was not a carefully designed brand strategy, but an accident from his tutoring work. In late 2015, he entered the tutoring industry due to substitute teaching; a colleague could not pronounce the English name Kurt, and seeing his profile picture was a cat, thus "Teacher Black Cat" was called out. 1
That job quickly turned the word "Teacher" into a reality of high working hours: classes, teaching materials, administrative support, websites, and Facebook, including periods of 12-hour workdays. The fan page was originally just an experimental field he dug out to reuse when he dared not test marketing techniques with the company account; when he resigned due to overwork, he discovered the page had already accumulated about 20,000 followers. 1
Here lies an important contrast: Teacher Black Cat did not have a brand first and then fill it with content; he first turned a failed streaming entry point into a name recognized by readers in the gaps between changing jobs. The later brand, which looks like a plan, is actually largely something left behind by time as an accident.

Lius Got the Likes First; History Made People Stay
Teacher Black Cat’s early online writing did not start with the "knowledge creator" persona. In interviews, he recalled using the ID "Salmon" in middle school, active on Bahamut and the BBS Benban, writing game guides, and serving as the moderator of Bahamut’s KUSO board. At that time, he treated writing as a game, treating article popularity as an unlockable achievement. 2
After the Facebook fan page was established, content ranged from netizen culture, current affairs commentary, and tutoring daily life, to GIF memes and cat photos. Lius was the most stable character: Teacher Black Cat once explained this interaction logic with a half-joking observation: "Humans will just like posts as long as they see a cat." 2
But cats did not explain why he could later write long articles. In 2016, a group of high school students dressed as Nazis and Hitler for a school anniversary, sparking media and social criticism; Teacher Black Cat first wrote a commentary, and then, prompted by netizens’ questions, wrote a primer on WWII and Nazi Germany. That article broke 10,000 shares in one day, and the fan page crossed from about 80,000 likes to over 100,000 likes. 1
This turning point is worth looking at slowly. The original action of "speaking up for students" did not stop at defending one side; it unfolded into a history lesson for unfamiliar readers. Teacher Black Cat admitted in the article that he did not agree with students playing Nazis, but also wanted to ask "why these children did so," and how society could avoid similar events happening again. 6
Therefore, his historical storytelling does not compress complex events into a few nouns; it starts from a scene seen by a Taiwanese person, then takes readers to more distant times. Published in 2018, History is War, by Yuan Shen Publishing, turns modern wars, international situations, and personal strategies into stories; the publisher positions it as a historical reader centered on ten important wars. 3
📝 Curator’s Note: Lius opened the door for him, but what truly made readers sit down was his willingness to finish explaining "why."
From High Reach on Facebook to Where the Eyes Do Not Allow
After the fan page grew, Teacher Black Cat did not stay only in text. Interview data shows he once signed with Facebook for game streaming, and later served as a community manager for a listed company and editor-in-chief for other large channels; but long-term live streaming caused dry eye syndrome, and in 2020 he ended Facebook live streams, entering a period of rest. 4
This is not a light, fast segment of "successful multi-platform operation," but rather the body pressing the pause button on platform strategy. When he had to reduce eye strain, voice became the medium replacing text. He produced Black Cat Radio, moving storytelling and interviews to Podcasts, and by inviting other creators to record programs, rebuilt a working method less dependent on screens. 4
In his later organized Podcast tutorials, Teacher Black Cat breaks production down into planning, equipment, recording, hosting, publishing, community, and continuous improvement; he does not package the show as a dream that can be completed with just passion. Equipment, a quiet recording environment, RSS feeds, platform review, and stable updates are all labor of creation. 7
A 2025 interview adds another layer of detail: he once did two seasons, over 50 episodes of Podcasts, initially out of curiosity about "what is being recorded," but later discovered this medium allowed him to talk more deeply with creators; but when full-time creation requires calculating return on investment, Podcasts also stopped updating because they were not making money. 8
This makes the word "transition" insufficiently precise. Teacher Black Cat did not move from Platform A to Platform B in one go, but constantly adjusted which type of creation was worth continuing amidst vision, income, interest, and audience relationships.
He Cuts One Fish into Articles, Videos, Audio, and Newsletters
Teacher Black Cat’s most frequently cited work method later is "one fish, many ways to eat." In a 2026 organized article, he describes how one piece of content becomes a newsletter article, then social media posts, videos, Podcast audio, and is cut into short videos; the same material does not need to serve only once, but each medium must be thought of in the pre-production stage. 9
His statement is direct: "The key to my survival these past few years is 'one fish, many ways to eat,' because it can lower costs." 9 The point of this sentence is not content recycling, but time. For someone who has not been a full-time creator for a long time, if every platform requires a brand new piece of content, creation quickly becomes another form of overtime.
Therefore, he segments platforms: easier-to-access content goes to the main channel, harder creations go to sub-channels, and insect topics have their own separate accounts. This is consistent with his early advice to creators: understand the target audience, and do not stuff all content into the same brand. 10
But multi-platform does not mean copying and pasting everything. Teacher Black Cat reminds us to think clearly before recording which segments can become short videos, articles, or audio files; the more pre-production thinking, the easier post-production becomes. This is a content view an engineer would understand: not infinitely converting the same data, but first designing a reusable structure.
📝 Curator’s Note: "One fish, many ways to eat" sounds like a traffic trick, but is actually more like a labor system that preserves creators' energy.
Newsletters Are a Path That Does Not Require Pleading the Algorithm First
In 2024, Teacher Black Cat began writing Black Cat Creative Newsletter. The reason he gave was not "newsletters are popular again," but that Facebook’s high reach made him start doubting who his readers actually were. He wrote: "Are my articles published for my readers to see? Or for the algorithm's AI to see?" 5
This question is also the core of the entire profile story. Teacher Black Cat is familiar with algorithms, knows how to increase interaction, and knows how multi-platforms drive traffic to each other. But the more familiar he becomes with the rules, the more he feels the rules are rewriting his tone. He worries that if every post only pursues high traffic, what is left at the end might just be another content farm. 5
So Black Cat Creative Newsletter is not just a new product, but an attempt to pull back the initiative. In his inaugural article, he said he wants to write about the funny stories, embarrassing moments, frustrations, and small tips from years of managing popularity for those who truly want to read. Not every reader needs this content, but those who need it can receive it directly. 5
Another public introduction in 2024 divides this project into four lines: "Black Cat Storytelling" for history and mythology, a newsletter for creators, "Like-Baiting Notes," and an organization of traffic, monetization, and tools. When a person remembered for cats and dry talk begins to publicly share his methods, entertainment and teaching are no longer two separate paths. 11
He also does not write the creator life as an advertisement for freelance freedom. Teacher Black Cat once reminded newcomers to first determine that they still enjoy doing this even if they do not make money. In another "mindset article," he wrote more directly about the high pressure of influencer work, unstable income, and the fact that effort and harvest are often disproportionate. 12 A 2021 career article also quotes him: after 5 years of managing a Facebook page and 13 years of online creation, only then could he make a living from freelance work. 13
This honesty is one of the few places in his content that does not rely on punchlines. Teacher Black Cat can describe traffic as "like-baiting," but does not hide the cost behind jokes: dry eye syndrome, long working hours, algorithmic uncertainty, and the gap between fans and income are all in the ledger of creation.
How One Person Avoids Being Trapped by Their Own Name
Teacher Black Cat’s public identity has many layers: English teacher, tutoring worker, community manager, Facebook streamer, historical storyteller, Podcast host, beetle and aquarium content creator, author, and social media coach. These names are not a pretty resume, but traces left after every change in platform and life conditions.
If you only look at the result of "influencer," you miss the most interesting part: what is truly stable for him is not the platform, but the ability to tell stories about unfamiliar materials that people are willing to listen to. Not a fixed form, but the willingness to relearn when forms fail. Reversing Education cites his viewpoint, treating "being a good learner and learning new things at any time" as a more important creator ability than a single skill. 14
In 2025, he talked about returning to Pingtung and truly devoting himself fully to his own channel. The same interview also records him dividing creators into "artist type" and "merchant type," but ultimately still placing physical and mental health and creative joy before income. 8 This is not denying commerce, but acknowledging that creation has two ledgers: one written in words, the other recorded in the body.
📝 Curator’s Note: What is most worth remembering about Teacher Black Cat is not how many platforms he understands, but that he knows every platform may require you to give up a piece of yourself.
That overheating graphics card in 2015 originally proved only one thing: this launch failed. But the fan page left by that failure was first filled with a cat, then pushed to strangers by a historical article, and finally brought back by the newsletter to the hands of those willing to truly finish reading.
This path has no fixed endpoint, nor is it as neat as "becoming a writer from being an influencer." A more accurate statement is: Teacher Black Cat has constantly changed media, yet repeatedly guarded the same question—when content can be cut into more formats and distributed to more platforms, is there still a type of creation that is for making someone truly understand, finish listening, and willing to stay?
