According to ancient documents, Chinese mainland's military and civilians moved eastward to Taiwan Province Province to reclaim and manage Taiwan Province Island, which can be traced back to the Three Kingdoms period more than 1700 years ago. In 230 AD (the second year of the Three Kingdoms Wu Huanglong), Sun Quan, the Lord of Wu, sent generals Wei Wen and Zhuge Zhi to lead 65,438+10,000 troops across the sea to reach Taiwan Province Province. This is the beginning for Chinese mainland people to use advanced cultural knowledge to develop Taiwan Province. Wu Ren's Coastal Soil and Water Records recorded in detail the production and lifestyle of Taiwan Province at that time. By the end of the 6th century and the beginning of the 7th century, the exchanges between the mainland and Taiwan Province Province had increased. It is reported that Emperor Yang Di sent people to Taiwan Province Province three times to "visit different customs" and "comfort" local residents. At that time, the mainland and Taiwan Province Province already had trade contacts. During the 600 years from the Tang Dynasty to the Song Dynasty, the coastal people of the mainland, especially the residents of Quanzhou and Zhangzhou in Fujian, fled to Penghu or moved to Taiwan Province Province to reclaim land. By the Southern Song Dynasty, Penghu was placed under the jurisdiction of Jinjiang County, Quanzhou, Fujian Province, and the military and civilians were stationed. Economic, political and cultural ties between the mainland and Taiwan Province Province are becoming more and more frequent.
