突發奇想！台灣數學老師在成人網站教微積分 Math tutor teaches on adult video site

　
A Taiwanese math teacher named Chang Hsu took to adult video platform Pornhub to teach calculus lessons, attracting 1.9 million views and nearly 7,000 subscribers to his account, bringing him wide attention and a total income of NT$7.5 million.

The 34-year-old said he had tried lecturing on YouTube but found it difficult to compete with similar channels. He started to branch out to the porn site and was surprised that this marketing strategy has brought him many new students.

Now that many fellow tutors have started to follow suit, Chang said he is planning a revision for his channel, which remains top secret for now.

一名台灣的數學家教張旭，居然突發奇想，在成人影片平台 Pornhub 放上他教授微積分課程的影片，瀏覽量超過 190 萬，訂閱人數近 7,000 人，因此引起廣泛關注，甚至為他帶來一年750萬新台幣的豐厚收入。

張旭今年 34 歲，他說過去曾嘗試在 YouTube 上架教課影片，但發現很難與對手競爭，他因此開始涉足色情網站，也很驚訝於這個行銷策略為他竟然帶來了許多新的學生。

如今很多老師都開始模仿他，張旭也有發現，並說他正在計劃對頻道進行改版，目前這仍然是最高商業機密。
