I want to know the answer to the following question:
How long has China been with centralized power?
All the background I'm provided with is that "On the other hand, Chinese nationalists are suspicious of decentralization as a form of secessionism and a backdoor for national disunity; still others argue that the degree of autonomy given to provincial-level officials in the People's Republic of China amounts to a de facto federalism.". Is that enough to answer the question?
Answer: no
