To avoid pursuit by the Japanese army, they left Chupung and moved to Annuchino, where the headquarters of the Russian partisan unit was located. In November, this unit merged with Han Chang-geol's Suqing army and Park Gyeong-cheol's New People's Corps (Shimindan) at Trechii-pujin, a Korean village in the Chuguyev Valley.
