What does Ottke mean?

During the Mongol Khanate period, the Su Nite tribe moved south from central Mongolia, that is, to the north of Zhangjiakou, which belonged to the eight Ottke of Chahar. During the period of Dayan Khan in Batu Munk, Su Nite tribe lived in a vast area from the north bank of Gannaoer in Curca, Abaga Banner to Gobi in Hang Gai, to Haoqite in the east and Siziwangqi in the west. During the period of Baodi Arakhan, his eldest son, Da Lishun, was led by Wu Jumuqin. The second son, Su Nite, was the leader of the State of Chu. During the period of Lidan Khan, due to the Manchu invasion of the Northern Yuan Dynasty, it was impossible to command the whole of Mongolia, and only Chahar households could be managed. At that time, 30,000 households in the west rebelled, and Horqin and Halaqin in the east were returned to Manchu, and the regime was unstable. When Ligudan Khan conquered 30,000 households in the west, Ujumuqin, Haozite, Su Nite and Abagaoteke of Chahar Department moved to Hang Gai to take refuge in Halaha. 1627 When Su Nite moved its capital to Hang Gai, it was divided into two flags: the left flag of Dabuhai Hushu, son of Chu Tiger in Baoerhai, and the right flag of Su Nite, son of Yin Bao, leader of Chaoerhongtaiji. /kloc-in 0/634, after the death of Li Dan Khan, his wife and son went to the Manchu Dynasty, hungry, and presented the imperial seal, which made the whole Chahar Ottke under the jurisdiction of the Manchu Dynasty. 1637, Tang, the son of Hu Shuqi, the leader of Dabuhai, got in touch with Khan of Manchu. 1639 On September 26th, the Manchu government agreed to establish the Zuo Qi and implement the dynasty flag system. From 1639 to 1946 * * about seventeen generations of county kings ruled the left and right flags of Su Nite.
