Alxa League
A member of the Borjigin clan, Darijaya was a descendant of Genghis Khan's younger brother Hasar. He was a prince of Alxa League, then administered by Ningxia. In 1925, he married Jin Yuncheng (), a member of the Manchu Aisin Gioro clan, daughter of Zaitao and cousin of Puyi. In 1931, upon the death of his father, he was named jasagh of Alxa Banner. In his new position he carried out various reforms, including closing the old yamen and establishing a new government staffed with young, educated people. In 1934, he was named a member of the Nanjing government's Mongol Local Autonomy Political Affairs Committee. Imperial Japanese Army general Kenji Doihara was known to have paid a visit to him, leading to suspicions regarding his loyalty. In March 1938, fearing that Darijaya planned to defect to the Japanese, Ma Hongkui had him detained and brought to Yinchuan on the pretext of ensuring his safety. He and his wife would be held under house arrest for more than six years. He returned to his banner in August 1944, and took up a position on the Kuomintang's 8th Central Committee.
