In 1279 AD, the Song Dynasty army and the Mongol army fought a large-scale naval battle at Yashan Mountain. When the Song army was completely destroyed and the Southern Song Dynasty was destroyed, Lu Xiufu committed suicide by throwing himself into the sea with the young emperor Zhao Fu on his back. Many loyalists followed, and 100,000 soldiers and civilians jumped into the sea and martyred the country. That's why someone asked such a question? Why not bring these hundreds of thousands of people to hide overseas in an attempt to make a comeback? The answer is not that you don't want to, but that you can't. As shown in the figure below, let's formulate several hypothetical escape routes and derive conclusions based on them. See if the Great Song can have a chance to make a comeback?
1. Hainan Island
This seems to be the most reliable recently, but it is not. Although Hainan belongs to the territory of the Southern Song Dynasty, it seems that it also has the greatest sense of identification with the Zhao and Song Dynasties. But it is not suitable as a counter-offensive base. Here's why:
A. The Yuan Dynasty, the retreat route of Hainan Island, also thought of it, so it captured Hainan Island before the decisive battle of Yashan Mountain.
B. Even Hainan Island is enough in the hands of the Great Song Dynasty: the distance between Hainan Island and the mainland is 39 kilometers wide from north to south, the narrowest is 19 kilometers, and the average width is less than 30 kilometers. This distance is too unsafe.
C. Hainan Island was a place of exile during the Southern Song Dynasty, and the property was barren. The weather is hot and miasma is rampant. There were also some indigenous peoples who were not conquered. Therefore, it is not realistic to be a base on Hainan Island, which is close to the mainland.
2. Taiwan Island
At that time, Taiwan was called Liuqiu, the largest island in China. If you refer to the example of Zheng Chenggong, it seems that taiwan can be divided. However, at this time, Taiwan was either a direct territory of the Southern Song Dynasty, or the central government did not set up a prefecture and a county in this area for direct administration. Therefore, even if the Great Song Dynasty was able to enter Taiwan, it had to guard against the attacks of the indigenous people on the one hand, and develop production on the other hand. Even hundreds of years later, after repeated development by the Zheng and Dutch, by the time the Qing Dynasty unified Taiwan, the total population of Taiwan was only 200,000. Feeding these populations was not entirely dependent on land output, but also from trade with Japan, Southeast Asia and Europe at the time. King Zheng of Yanping also wanted to use Taiwan as a base to counterattack the mainland, so he implemented a mature system of tun tian and conscription in Taiwan. After several generations of development, the population base exceeded 200,000, and it is conceivable how poor Taiwan's output was at that time. If according to the level of development during the Southern Song Dynasty, Taiwan can be used as a place to stay, but if there is a comeback, it is simply not possible.
3. Southeast Asia
According to the "Song History Volume 489 Column Biography 248 ◎ Foreign Five", the champa City Zhenla Bagan Li Li San Fo Qi Jia Bo Bo Ni Zhu Ren Dan Mei Liu and other countries were basically vassal states of the Song Dynasty, or regular tributes and so on. It is estimated that this is also the case, because the foreign warfare ability of the two Song Dynasties is not outstanding, so it is unlikely that the clan will submit to fear. However, if the Great Song Dynasty was destroyed, it went to defect and even wanted birds to occupy the magpie's nest in an attempt to counterattack the mainland. The final result is estimated to be the same as that of the Southern Ming Yongli Emperor, even if he fled to Burma. In the end, it must be offered to the enemy for peace. If you say that the population of the Angkor Dynasty is larger, it is okay, but people are the time when the cattle are broken. The Angkor Dynasty was established and Chenla was reunited. The Angkor Dynasty bordered the Tang Dynasty and the Ming Dynasty. At its peak, the Angkor Dynasty occupied all of present-day Cambodia, thailand and most of Laos, Vietnam and southern Burma, and was the most powerful country in Southeast Asia's history. Will this dynasty set aside territory for us? If anyone says that these countries worship purely with a bag on their heads when they see the heavens upwards. So the way to Southeast Asia is also not passable.
4, Japan
The Japanese view is that "there is no China after the cliffs." When the Chinese civilization is strong, Japan will send emissaries to learn and absorb advanced cultural knowledge back to Japan to enhance its national strength. If the exiled imperial court went to Japan, the result must be very bad. Without going into detail, let's make up for it.
I am the emperor of history, welcome your attention; if there is a flaw, the axe is right.
