Why is China often a centralized state, while the West has no Rome after Rome? Seeking an answer.

Remember Huang Renyu's view that China was a precocious civilization. China's civilization flourished in the Yellow River basin. During the Spring and Autumn and Warring States Periods, the Yellow River flooded many times (I can't remember the exact number, but it was frequent anyway), and the countries in the middle reaches of the Yellow River were beggar-thy-neighbor and took advantage of the fire, and it was the time when everyone realized that they needed a united regime in order to deal with these kinds of big problems. The unification of the world then became the will of the people. After the Qin Dynasty, the unification of writing and weights and measures increased the national centripetal force even more.

The West, in contrast, did not try to make all its subjects feel the same way during Roman rule. Rome actually sent generals to rule over various localities, similar to the feudal system. There was no unified identity for Rome among the lower classes. After Rome Clovis almost created another great empire after Rome, but due to barbarian invasions within Eurasia and later disputes between popes and emperors, it finally failed to create a centralized Europe-wide state similar to China.

West and East took different paths
