孝子芋

英廟癸未。先君子入日本。李七灘匡呂書托種藷法。至對馬島佐須浦始得之。卽所稱孝子芋也。古有孝子種之養親故名。 [Korean Literary Sinitic, trad.]Yeongmyo gyemi. Seon'gunja ip Ilbon. I-Chiltan-Gwangryeo seotak jong-jeo-beop. Ji Daema-do Sasu-po si deuk ji. Jeuk soching hjoya-u ya. Go yu hyoja jong ji yangchin go myeong. [Sino-Korean]1763. My deceased father had went to Japan; Lee Chiltan Kwangryo sent a letter on the cultivation of potatoes; at Sasuna on Tsushima island he first attained this; namely, what is called the hyoja-u ("potato of the filial son"). There was a filial son who cultivated it to raise his parents, hence its name.
