Use historical facts to prove that Xinjiang, Tibet, Taiwan, and Heilongjiang have been our territory since ancient times?

Taiwan

In ancient times, Taiwan was connected to the mainland. Later, due to crustal movement, the connected parts sank into the sea, forming a strait and the island of Taiwan appeared.

Taiwan’s recorded history can be traced back to 230 AD. At that time, Sun Quan, King of Wu of the Three Kingdoms, sent 10,000 officers and soldiers to "Yizhou" (Taiwan). Wu Shen Ying's "Linhai Land Chronicles" left the earliest record of Taiwan in the world. During the Sui and Tang Dynasties (589-618 AD), Taiwan was called "Liuqiu". The Sui Dynasty visited Taiwan three times. According to historical records, in 610 (the sixth year of Sui Dynasty), Han people began to immigrate to the Penghu area. By the Song and Yuan Dynasties (AD 960-1368), there were a considerable number of Han people in the Penghu area. After the Han people opened up Penghu, they began to develop into Taiwan and brought with them the advanced production technology of the time. In the middle of the 12th century AD, the Song Dynasty placed Penghu under the jurisdiction of Jinjiang County, Quanzhou, Fujian, and sent troops to guard it. The Yuan Dynasty also sent troops to Taiwan. The governments of the Yuan and Ming dynasties set up an inspection department in Penghu, which was responsible for patrolling, detecting criminals, and also running salt classes. In the late Ming Dynasty, the scale of development became larger and larger. In the era of war and famine, the Fujian authorities of the Ming Dynasty government and the Zheng Zhilong Group once organized organized immigration to Taiwan.

Xinjiang

Xinjiang, the most original name is Zhuzhou, and the Han Dynasty called it Xiyu, which means the territory of western China. This name appeared in Chinese historical records from the Han Dynasty and was used until the Qing Dynasty. Unified Xinjiang, later renamed Xinjiang.

The true and specific records of the geographical history of the Western Regions in ancient Chinese history began in the Han Dynasty. Also in the Han Dynasty, the central government began to set up local government agencies in various parts of the Western Regions. Therefore, since the Han Dynasty, the Western Regions have been an integral part of our country. By the early Western Han Dynasty, the social economy in the north and south of the Tianshan Mountains had developed greatly.

Tibet

Tibet: named after the official name of the Qing Dynasty. In the Tang and Song Dynasties, it was Tubo; in the Yuan Dynasty, it belonged to the Xuanzheng Yuan; in the Ming Dynasty, it was called Wusi Zang, with the capital and other departments; in the early Qing Dynasty, it was called Weizang, with Wei meaning front Tibet and Zang meaning rear Tibet; later it was officially named Tibet, which was the beginning of Tibet’s name; in the Qing Dynasty, it was called Weizang. It was established as the Minister of Tibet Affairs; it was the place of Tibet in the early Republic of China; it was still there after the founding of the People's Republic of China, and later it was changed to the Tibet Autonomous Region, and the name of the region has not changed to this day.

Heilongjiang

The Heilongjiang River Basin was included in the territory of China as early as the middle and late Tang Dynasty and became a major inland river in China. Later it became the territory of the Liao Kingdom. In the Yuan Dynasty, it was once again included in the territory of China and became Inland river of Yuan Dynasty. Since the signing of the Aihun Treaty in 1858, which China considered an unequal treaty, Heilongjiang began to form the border between most areas of China and Russia. When the Eight-Power Allied Forces marched toward China in 1900, Russia sent troops across Heilongjiang on the pretext of protecting the China-Russia Railway, set fire to Aihui City, which belonged to the Qing Dynasty at the time, and caused the Hailanpao Massacre, about 40 kilometers deep into the Qing Dynasty's border. Soon the war ended, and the 64 villages in Jiangdong that were originally under the jurisdiction of the Qing government were occupied by force.
