Most Seogi were progressive Yangban, as the scribes had to have literacy. Meanwhile, the Seongchal were town police, who administered the law and reported corrupt officials or Yangban to the Dongmong and Posa. Most Seongchal were killed in the Second Revolt. Dongmong were young men who arrested, imprisoned, or even flogged those reported by the Seongchal. They also had a powerful hatred for Yangban, often castrating them and using Yangban women to light candles or pour water. Dongmong also led to a curious marriage practice called 'three-day marriage'. Dongmong, searching for partners, hung white scarves on the door of a house of a Yangban who had an unmarried daughter. This meant that the daughter had to marry the Dongmong. To escape the forced marriage, fathers often found another suitable young man and made the daughter marry him within three days in secret. By November, three-day marriage had become so prevalent that the only virgins left were girls under fourteen years of age. Meanwhile, the Posa were mostly tiger hunters who served effectively as soldiers, cooperating with the Seongchal and Dongmong to fight against Yangban resistance. The rebels referred to their cause as the "Dongdo" (another name for 'Donghak') and to their army as the "Dongdo Euibyeong", the "Righteous army of Donghak". Rebels called themselves 'Hajeob', after the lowest Donghak initiate, and called any other person, even children, 'Jeobjang', a rendering of Jeobju. While the First Sino-Japanese War raged on, Japanese troops occupied Seoul and made a pro-Japanese government there. Before the Battle of Pyongyang, Jeon's strategy seems to have been that he would crush the fleeing Japanese from the south while the Chinese soldiers chased them from the north. However, his prediction proved wrong, with a major Chinese defeat in Pyongyang. Jeon decided that he should defeat the Japanese by taking control of Korea and severing Japanese supply lines. However, knew he would have to get the support of the Northern Jeob, who commanded all Donghak outside "Jibgangso"-controlled areas. Choe Sihyeong was staunchly anti-rebel, as he feared that a large-scale rebellion based on the Donghak religion would end with the destruction of Donghak. To escape persecution, the Northern Jeob had to fight against the largely Southern Jeob rebels.
