Why did Zhu Yuanzhang make Nanjing the capital instead of Hefei?

In the Central Plains, there have been two important places since ancient times, Nanjing and Hefei, but these two city brothers have different fates. Nanjing was once the ancient capital of the Six Dynasties. Many regimes have chosen Nanjing as their capital, such as the Soochow regime in the Three Kingdoms, the Sima regime in the Eastern Jin Dynasty, the post-Song, post-Qi, post-Liang, post-Chen and southern Tang Dynasties in the Southern Dynasties, including the Ming Dynasty. But Hefei still wants to be forgotten, and no regime has considered choosing it as the capital.

It turned out that there was a Zhu Yuanzhang in Anhui, and the Ming Dynasty he founded also chose Nanjing as its capital. Zhu Yuanzhang once took Fengyang as the capital and made great efforts to build it into the capital. According to the truth, the geographical location of Hefei is far more important than Fengyang, so we should focus on Hefei. What the hell is going on here? In fact, Zhu Yuanzhang specially thought about this problem. Nanjing has Purple Mountain, just like Long Mai. Choosing its capital must be a continuation of rule to bless this country. Since the geographical location of Hefei is so good, it is necessary to stay in Kyoto, just like the relationship between Beijing and Tianjin.

China's ancient political and economic centers were all in the Central Plains. To attack the south of Nanjing, you have to cross the river to fight. The Ming Dynasty established by Zhu Yuanzhang overthrew the Yuan Dynasty, so when the capital was established, it was always wary of the counterattack of the Yuan Dynasty. At that time, shipbuilding and bridge-building techniques were underdeveloped, and the Yangtze River and Huaihe River became natural moats. In order to break through Nanjing in one fell swoop, we first went straight to Nanjing from Wuhan along the river, but Hefei could intercept it; The second is to start directly from Hefei and enter the Nanjing border via Chaohu Lake; The third is that the direction of Yangzhou is from south to north, but the enemy was in the north at that time, so this shows the importance of Hefei to Nanjing.

Cao Cao wanted to destroy Wu Dong. He launched two battles, one was Battle of Red Cliffs, and everyone knew that the other was the Battle of Hefei. At that time, Cao Cao was defeated by a series of stratagems in Chibi, and he was unwilling, so he attacked Nanjing from Hefei, so Cao Cao and Sun Quan competed for Hefei for more than 40 years. Later, after Cao Cao acquired Hefei, he established a military town, attacked Nanking from Hefei, wiped out the Wu Dong regime, and finally unified the whole country. In fact, Sun Quan also wants Hefei, not only to defend Nanjing, but more importantly, he also has a hegemonic heart, and he also wants to go north in Hefei.

There is also the outbreak of the Feishui War in the Eastern Jin Dynasty, which indirectly proved the importance of Hefei. It is because of years of war that people realized Hefei, but its importance lies in the military. As the capital of a country, there are also political, economic and cultural factors. Therefore, the Six Dynasties chose Nanjing, because after Nanjing was established as the capital, as long as Hefei mastered it, there would be no worries. Moreover, since the Qin Dynasty, Chang 'an and Luoyang have been the capital cities, followed by Kaifeng and Hangzhou, and then Nanjing and Beijing. Hefei basically played the role of Tianjin Wei, so it never became the capital of ancient dynasties.
