Which Kyushu did the land of Kyushu refer to during the Three Kingdoms period?

The Three Kingdoms Kyushu is an ancient Kyushu, which was founded by Cao Cao. Liu Bei and Sun Quan disagreed.

The administrative division system of the Eastern Han Dynasty was 13 state for a long time, but Dahan also had 14 state.

The familiar 13 states are: Qingdao, Right, Binhe, Hebei, Yanzhou, Xu, Yu, Yang, Jing, Yi, Jiao and Liangzhou.

14 is Yongzhou, which was separated from Liangzhou in 194.

Xian Di: In the first year of Xingping, Bingzi was divided into four counties, Hexi and Liangzhou, and served as the governor of Yongzhou in summer and June.

Handan merchants and Xu Yi have historical records. Before Cao Cao returned to Kyushu, they were both secretariat of Yongzhou. But it was later sent back to Liangzhou.

Compare the status. In the eighth year of Jian 'an in the Eastern Han Dynasty (AD 203), the Toe Toe Secretariat was changed to Jiaozhou, which now governs China, Guangdong, Guangxi, northern and central Vietnam, and the state governs Panyu. That is, 203 years ago, Jiaozhou was not a state.

The picture below shows Xia Jiuzhou. Cao Cao once wanted to change thirteen states into ancient Kyushu.

At the end of the Han Dynasty, there were only 9 counties in Jizhou, but after the restoration of Kyushu, there will be 32 counties in Jizhou, with the largest number of counties.

Cao Cao later got 10 counties as fiefs in Jizhou, which was more than all counties and countries in Jizhou under the administrative system of the Eastern Han Dynasty. If Kyushu is gone, Cao Cao, who was promoted, could not get so many fiefs properly.

Remarks: don't just look at the area when looking at the site. It depends on how many counties there are, representing population, labor force, economic source and soldier reserve. During the Three Kingdoms period, although some people went south, the population was less than that in the north. Although the area is very large, they are all undeveloped and desolate places.
