Taking history as a mirror, all previous civil wars in China were won by the north in the end. Is there a reason for geographical feng shui?

This has something to do with the geography of our country. From northwest to southeast, the terrain of our country gradually decreases. In ancient wars, the party occupying favorable terrain had a greater chance of winning in the end. There are many plains in the north and many hills and mountains in the south. The horse-producing areas are concentrated in the north. Needless to say, the status of war horses in ancient wars. As soon as the Confederate army entered the plain, there was little chance of winning when it met the other cavalry. Of course, these are only some factors. In addition, the ancient north was the political, cultural and economic center of our country. The overall productivity level is much higher than that of the South (after the Northern and Southern Dynasties, the South gradually surpassed the North economically). The only person who succeeded in unifying the south and the north was Zhu Yuanzhang of the Ming Dynasty. This is the only one without branches. His success is another problem. However, its strategy and tactics initiated from south to north have immeasurable influence on later generations.
