Taiwanese math teacher Chang Hsu took an unusual step in his teaching career by using the adult website P*rnhub to teach math. This bold move has made him famous worldwide and earned him over ₹2 crore (around $269,000) a year. Let’s see how Chang turned his teaching career around with this surprising approach.
Breaking Traditional Educational Barriers
Chang Hsu, 34, has been teaching math for over 15 years and holds a Master’s degree in mathematics. Even with his qualifications, he struggled to stand out on traditional platforms like YouTube, which are full of competitors. That’s when he came up with the idea of posting his calculus lessons on P*rnhub, a site mainly known for adult content.
While this decision seemed strange at first, it turned out to be very successful. By May 2020, Chang’s channel had gained nearly 3 million views and 13,000 subscribers under the username “changshumath666.” His math lessons quickly became popular. He used the catchy phrase “Play Hard, Study Hard” to promote his videos.
Why P*rnhub?
Chang chose P*rnhub for a smart reason. He noticed that many young adults and college students, who are his target audience, often visit adult websites. By placing his lessons on a platform where these students already spent time, Chang found a space with little competition. His videos, which last about an hour and cover complex math topics, are presented in a casual and engaging style.
He is usually seen wearing his signature grey hoodie, making math problems easier to understand. Although some viewers watch his videos more for entertainment than education, his unique approach attracted students who later signed up for his paid courses outside of P*rnhub, helping him earn more money.
Financial Success and Global Reach
Chang’s decision to use an adult website for teaching has led to great financial success. He earns ₹2 crore annually, not only from P*rnhub but also from his paid courses. His teaching style has caught the attention of students worldwide, with many of them coming from outside Taiwan.
Chang has tried to expand to other adult websites but faced problems with their rules, as they were not as accepting of non-adult content.
A New Era in Digital Learning?
Chang’s success shows that stepping away from traditional platforms can lead to new opportunities in digital learning. His story also raises important questions about the mix of education and entertainment, and whether unusual platforms can be used for teaching.
While some may find his choice controversial, it has opened up a new conversation about how teachers can reach more students in a crowded online space.
Disrupting Norms with Creativity
Chang Hsu’s journey from a regular math teacher to a global sensation on P*rnhub shows the power of creative thinking in education. His unique approach has brought him both financial success and international fame. For Chang, “Play Hard, Study Hard” isn’t just a slogan—it’s a strategy that has worked in many ways.
