Before the Ming Dynasty, the north was always the region with the richest resources and talents in the Central Plains. The Cao Wei regime occupied most of the northern areas, and the agricultural base occupied by Sun Quan and Liu Bei was underdeveloped, with unbalanced education and inconvenient transportation. Judging from the future development potential and present situation, the Cao Wei regime has the strength to unify the world. With the passage of time, Cao Wei's regime will become stronger and stronger, while Sun Liulian will become weaker and weaker, which is the fundamental reason why Sima family can finally unify the whole country, regardless of its development potential or current strength.
The Northern Zhou Dynasty and the Western Wei Dynasty in the post-Three Kingdoms era have great potential for future development, although they lacked strength in the early stage. These two countries are potential stocks. When the war broke out constantly, the local forces outside were expanding their strength. They chose the policy of keeping a low profile, constantly introducing new talents and developing their own strength. In other countries, the two countries have achieved a relatively stable development period, thus greatly increasing their competitiveness and creativity in the future.
The future is reserved for those who are prepared. The Northern Zhou Dynasty and the Western Wei Dynasty did not argue for a while, but they had a longer-term goal, so they dominated the later development goals.
