In history, chaos occurred in all dynasties that implemented the parallel system of counties and countries, such as the Seven Kingdoms Rebellion in the Han Dynasty and the Jingnan War in the Ming Dynasty. History has proved that the county-state parallel system does not conform to historical development. Gu was a thinker in the late Ming and early Qing Dynasties. At that time, the autocratic emperor had been hated by progressive thinkers. So he said, "Today's monarch is not enough for our county. Everyone suspects it and everything is under control." Although the emperor owns counties and cities, he is still not satisfied. He suspects anyone casually and has to intervene in everything, which is obviously a strong dissatisfaction with the emperor's autocracy. He only opposed absolute monarchy, not monarchy, because it was impossible to put forward a democratic system in the modern sense because of the limitations of the times and historical conditions at that time. Therefore, after the above analysis, item C is correct.
