According to the discussion conducted by Dashdawa Mongol representatives in the video, they have always been officially recognised as Mongol since the Qing period till today. During the Cultural Revolution, however, under pressure, many Mongols changed their nationality registration to Han Nationality. Kou Zixin is one of the people who changed their nationality register, but he wants to change it back to Mongolian. He says it is a complicated process requiring a lot of certification. Wang Yanhong, however, successfully restored his nationality to Mongolian, which now appears on his ID card.
