30-second overview:
Tsai A-Ga (Tsai Wei-chia) is a legend in Taiwan's influencer world. He was the first creator to reach one million subscribers, and in 2022 he led his eldest son Tsai Tao-gui to set a world-class record as the "youngest million-subscriber influencer." Behind the surface of comedy and "showing off the kids" lies the professional architecture of a man with a master's degree in social welfare. This article takes a deep look at how Tsai A-Ga wove his social work expertise into an eighteen-year creative career, and how he chose to return to his calling at the peak of his traffic — using action to respond to the childhood memory of having been helped.
"1984. Chiayi. A child from a single-parent family who lost his father at the age of eight."
This is Tsai A-Ga's real life starting point — it sounds like a TV drama, but every word is true. Behind the manic comedy and fluent Taiwanese on screen, Tsai A-Ga's growth trajectory is filled with the shadow of the social welfare system. He has mentioned in interviews that he grew up receiving government assistance and relying on relatives for support.1 That experience of having been helped, when he gained admission to Soochow University's social work department and later pursued a master's degree in social welfare at Chinese Culture University, crystallized into the deepest foundation of his career.
Curator's note: Rather than calling Tsai A-Ga a successful businessman, it is more accurate to call him a social worker who knows how to package "social observation" in traffic.
The First Counter-Intuition: "Social Welfare Studies" Hidden Inside Comedy Videos
In 2008, Tsai A-Ga accidentally went viral with an angry video burning the Beijing Olympic Games flag. At the time, YouTube in Taiwan's internet environment was still just a hard drive for storing videos — no one imagined it could become a career. But Tsai A-Ga began systematically producing a series of "Love Taiwan" videos — teaching Taiwanese, introducing Taiwanese street food, and complaining about social conditions.
If you look carefully at his early work, you'll find more beneath the comedy surface. His master's thesis research was on "labor market exclusion of urban indigenous peoples,"2 which through in-depth interviews uncovered the structural discrimination and identity dilemmas facing indigenous university graduates in job seeking. This sensitivity to social margins and ethnic identity was channeled into a fierce defense of Taiwanese local culture in his videos. Using the most grassroots, most direct language, he turned serious cultural identity issues into five-minute short videos everyone in Taiwan could laugh through.
Tsai Tao-gui: The "Privacy and Education" Experiment Behind the Youngest Million-Subscriber Record
In 2018, eldest son Tsai Tao-gui (Tsai Wei-ting) was born, and Tsai A-Ga's channel entered its "parenting era." In 2022, four-year-old Tsai Tao-gui officially broke through one million subscribers, setting a record as the youngest person ever to reach one million subscribers in Taiwan — or even in Asia.34
But enormous controversy came with the traffic. In 2020, Tsai A-Ga rented out an entire Taoyuan Metro station to hold a second birthday exhibition for Tsai Tao-gui, triggering fierce criticism about "over-exploiting the child" and "privilege."5 Facing accusations of "making money by showing off kids," Tsai A-Ga publicly released data to counter this, emphasizing that he was not near the top of parent KOL rankings and that his primary motivation was to "document growth."6
Curator's note: Tsai Tao-gui's success reflects the most brutal and most tender contradiction of the influencer industry: when growing up becomes a product, how do you draw the line between privacy and love?
To protect his family, Tsai A-Ga formally filed suit in 2024 against internet trolls who had fabricated and implied things about Tsai Tao-gui, emphasizing that "some jokes are not acceptable."7 At the same time, he wove sex education content into his videos (such as taking Tsai Tao-gui through reading about sperm and eggs), attempting to transform "documentation" into content with genuine educational value.
The Critical Turn: When "Tsai Wei-chia" Met "Tsai A-Ga"
In 2014, Tsai A-Ga became the first creator in Taiwan to break through one million subscribers.8 This was a milestone — and a massive challenge. As the influencer industry entered its warring-states era, new generations flooded in one after another; many creators burned out within two or three years, but Tsai A-Ga lived through eighteen. As of early 2026, he has held the top position of the top-100 influencers continuously, holding multiple million-subscriber channels, and is mocked by netizens as the legend of "Old Soldiers Never Die."9
His longevity secret lies in his focus on "people." From individual creation to founding "Big Buddha Studio," he applied the "client-centered" thinking emphasized in social work to audience cultivation. Behind the videos is long-term cultivation of a virtual Taiwanese community.
Challenge and Betrayal: The Real Price Behind the Traffic
The path of longevity was not without turbulence. In 2020, Tsai A-Ga and his pregnant wife Erbo were attacked by individuals dressed in black on the street, shocking all of Taiwan. In 2024, the even more explosive "AB contract" betrayal by senior employee Laura (Lin Pei-chen) emerged.10 This trusted confidante, who had worked alongside him for years, exploited contract loopholes to privately pocket tens of millions of NT dollars in company revenue. For Big Buddha Studio, which emphasized "trust" and a "family feel," this was an undeniably heavy blow.
The Afterword: "Vocation" After Selling the House
"Founding the association is not a project, not a side business — it is a vocation."1
In 2022, before his thirty-eighth birthday, Tsai A-Ga announced the founding of the "Home Sweet Home Social Welfare Association." To raise funds, he sold the house he had lived in for six years, full of memories. The children he wanted to help were those who, like himself back then, had "ordinary origins but talent."
Starting in 2023, the association launched the "Outstanding Talent Scholarship" and "SFC University Welfare Club" programs,11 investing millions of NT dollars each year. In 2026, the association further deepened its "Children and Youth Empowerment Program" and brought the "hahababay" pop-up shop into remote indigenous communities, combining brand and public good to bring warmth.1213
He once said with emotion: "I hope that through our encouragement, these children can see hope and transform their lives!"1
That sentence brought him from being an "influencer" back to being a "social worker." At the peak of his traffic he turned around, attempting to prove that the ultimate destination of internet influence should not be only commercial advertising — but can be something with far deeper social impact.
Curator's note: A social work student spent fifteen years and finally, through another path, filed his "case closure report."
