Pyong-oh, der schon damals ornithologisch interessiert war, beendete im Sommer 1950 die Ausbildung an der Tierzuchtfakultät der Landwirtschaftlichen Hochschule in Wonsan und fand hier eine feste Anstellung. Sie endete jedoch bald, da im Juni 1950 der Koreakrieg ausbrach. [Pyong-oh, who even then was interested in ornithology, finished his training at the animal husbandry department of Wonsan Agricultural College in the summer of 1950 and found a steady job there. But this soon ended, as in June 1950 the Korean War broke out.]
