In 304 AD, Liu Han and Cheng Han were founded; In 439 AD, Beiliang was destroyed by the Northern Wei Dynasty.
The sixteen-country troubled times, which lasted for 136 years, finally ended and the north was reunified.
It's not the players from sixteen countries who have been playing in troubled times for a hundred years, but TaBaWei who is hiding in sixteen countries.
In 386 AD, Tuoba GUI took advantage of the division of the former Qin Dynasty and the chaos in the north to rebuild the country and make the capital prosperous.
In 398 AD, Tuoba GUI, the ruler of Wei, changed his country name to Wei and moved his capital to Pingcheng (now Datong, Shanxi).
At this time, the Northern Wei Dynasty was able to rely on Bingzhou in Shanxi and look around the world, so it was possible to compete for hegemony in the Central Plains.
The so-called land of victory has two elements: first, others can't beat you; Second, you hit others, just hit them.
The first and most important point is that others can't beat you.
Therefore, the key is not how many victories you can win, but how many defeats you can bear if you win by form.
Both Guanzhong and Shanxi have such geographical features.
There are four passes to win in Guanzhong, and Guanzhong is a thousand miles away in Huang Jincheng, so it is very difficult to buckle off.
Guanzhong is not blocked: the west can pass through the western regions, the east can enter the Central Plains, the south can take Jingzhou, the north can sweep the north, and it is easy to get out.
Shanxi has a good terrain, with the Yellow River in the south, Luliang Mountain and Yellow River in the west, Taihang Mountain in the east and the Great Wall in the north. Located in the highlands with mountains and rivers, Shanxi is difficult to fight.
If Shanxi is not blocked, it can enter Guanzhong area to the west, Hebei area to the east, Henan area to the south and grassland to the north across the Great Wall. It is easy for Shanxi to send troops.
Therefore, when the world is in chaos, Sheng Xing in Shanxi can replace Sheng Xing in Guanzhong, but it can't start the Shanxi era alone.
