In 1827, southern part of Xinjiang was retaken by former ruler's descendant Jihangir Khojah; Chang-lung, the Chinese general of Hi, recovered possession of Kashgar and the other revolted cities in 1828. A revolt in 1829 under Mohammed AH Khan and Yusuf, brother of Jahangir Khoja, was more successful, and resulted in the concession of several important trade privileges to the district of Alty Shahr (the "six cities").
