The tea fields established in Boseong during the Japanese colonial period were severely devastated by the Korean War. The scars left by the war extended directly into this region's industrial foundation as well. It was against this backdrop that, in 1957, Jang Yeong-seop, chairman of Daehan Dawon, took over the devastated tea fields and the surrounding woodland, creating a turning point.
After establishing Daehan Dawon Co., Ltd., Jang Yeong-seop set about newly cultivating large-scale tea fields on the barren slopes of Mount Hwalseongsan, standing 350 meters above sea level, and the surrounding areas of Mount Obongsan. According to Daehan Dawon, he planted approximately three million ornamental trees around the tea fields — cedars, Japanese cypresses, ginkgo trees, and maples — and, in addition, some 5.8 million tea trees. Combined, more than eight million trees transformed the mountain that had been left bare by the war into a tea garden resembling a laid-out green carpet. The landscape that symbolizes Boseong today was not the product of nature recovering on its own, but rather the result of one entrepreneur's determination and a massive tree-planting effort.
