Taipei, Nov. 2 (CNA) If you search for videos using hashtags like "classroom," "graduate student" and "real person" on adult video platform Pornhub these days, you may end up with hardcore calculus lessons provided by Taiwanese math teacher Chang Hsu (張旭).

Defying expectations, Chang has attracted 1.9 million video views and nearly 7,000 subscribers to his account, bringing him international attention and interview requests from the adult website.

"I knew this day would come," the 34-year-old told CNA. "People get intrigued if you do special things in special places."

In his roughly 230 videos, Chang can be seen fully clothed in his trademark gray hoodie, teaching math in Mandarin for as long as one hour, attracting comments such as "Asian porn is strange."

Although Chang admitted that he felt a majority of his viewers visited his account, dubbed "Play hard, study hard," for a laugh rather than to study math, he said such a marketing strategy has brought him many new students.

Chang said the students, many of whom were from other countries, watched the free lessons on Pornhub and decided to enroll in his paid classes through various platforms, which altogether earned him NT$7.5 million (US$268,000) per year.

"The online-teaching market is highly competitive, and I can now attract 1,000 students each year, compared with an average of a few hundred for a calculus tutor," said Chang, who began the Pornhub project in May 2020 after a financial crisis at his cram school.

Holding a master's degree in mathematics with 15 years of teaching experience, Chang said he had tried lecturing on YouTube but found it difficult to stand out from his competitors.

"I asked myself where to find my target students, say college boys, and the answer popped out: adult video platforms," he said.

Not all such websites appreciated Chang's idea, however, as others including XVideos and NXNN rejected non-adult clips, he said.

Now that many fellow tutors have started to follow suit, Chang said he is planning a revision for his channel next month.

"This is a top business secret, and what I can only tell you is it will no longer be just me in the videos," he said, implying, perhaps, a new hashtag of "multiple people."
