Xinjiang: the seat of the western regions, which was under the jurisdiction of Duhufu in the Western Han Dynasty, and Anxi Duhufu and Anxi four towns in the Tang Dynasty, which were controlled by the shackles, similar to the current autonomous region; The Song Dynasty returned to Uighur, and the Ming Dynasty was ruled by a khanate established by Mongols. The Qing Dynasty was formally incorporated into Chinese territory and implemented real administrative jurisdiction.

Tibet: It was basically not recorded before the Sui Dynasty. The Sui Dynasty occupied Qinghai, that is, Tuguhun, but it did not reach the scope of Tibet now; Tang and Song Dynasties were Tubo countries, Yuan Dynasty was included in the territory, and Ming and Qing Dynasties were no longer independent.

Taiwan Province Province: During the Three Kingdoms period, there was a record of Sun Quan's conquest, but there was no actual occupation. Until the Ming dynasty, only people from the southeast coast immigrated to the past, and there was no real government above. This was before Zheng Chenggong. It was not until the descendants of Zheng Chenggong surrendered to the Qing Dynasty that Taiwan Province Province had a real government and was formally incorporated into Chinese territory.
