36歲的蔣友柏第一次親筆寫下人生第一本書,並為書中的專屬APP音樂程式寫歌,書名『第十九層地獄』,一如他向來語不驚人死不休的性格,儘管總被落在媒體大標題上引發爭議,但他依舊選擇誠實發言,不在乎大家怎麼看他,「這就是我,不然你咬我啊?」At the age of 36, Demos Chiang personally authored his first book and wrote a song for the book’s exclusive APP. The book is titled “Hell Bible”, just like his outspoken personality, although his words often stir up controversies in the media, he chooses to be true to himself and speak in the most honest and outright manner. He doesn’t care about how others perceive him, “Bite me, this is who I am”.
