Eight months, one line of lyrics "Nobody Knows" was the first time that people took note of Tsai Chen-nan, who was managing a hat factory in the countryside outside of Taichung. "Everybody thought that this guy had really gotten something rolling," says Hu Tai-li, a researcher at the Academia Sinica who also happens to be Tsai's aunt.
一句歌詞想了八個月「心事誰人知」是原居於台中鄉下經營帽子工廠的蔡振南，第一次被社會發現，「讓大家感覺他這人似乎有些什麼的開始」，中央研究院研究員、也是蔡振南嬸嬸的胡台麗說。
