Master singer Jeong Eung-min learned from his uncle Jeong Jae-geun, who had in turn inherited the singing of Bak Yu-jeon, the founder of the seopyeonje style (the lineage running Bak Yu-jeon → Jeong Jae-geun → Jeong Eung-min). But over time, he grew troubled by what he saw as a general coarsening of pansori singing, and he ultimately chose to return to his hometown of Hoecheon-myeon in Boseong County. He set aside the glamour and renown of the stage to retreat into his hometown and devote himself entirely to his art.
Jeong Eung-min then took in disciples and taught them, synthesizing in his own way the seopyeonje and dongpyeonje traditions of pansori he had learned from various masters into a single, distinctive school. This school came to be known as "Boseong-sori," named after the region where he had settled. Later master singers, including Seong U-hyang, Jo Sang-hyeon, and Seong Chang-sun, carried on this tradition of Boseong-sori and continue to pass it down today. A single singer's personal decision to turn his back on prevailing trends and retreat to his hometown ultimately turned a place name itself into the name of an entire pansori school.
