The Uighur had propers tremendously in recent years due to great influx of local and foreign tourist. They had nothing to complain. Kashgar is now quite modern due to the chinese building almost a new city by its side. Tourists came not only for the great amount of spectacular landscapes but also the fasinating cultures of minorities and the food There is no videos on Tajiks living on the Pamirs or the Kherghis in the Karakoram.There are Russian in Zhaosu. Kazil grottoes amazing.
You are lucky that Han people had treated Uighurs as part of its people due to nationalism in China. In recent years Han people spent their new found wealth on travels and food which benefited the minorities here. Is a matter of personal perception that they treat Uighurs as sub Han.
