What are the six provinces in Central Plains?

The six provinces in Central Plains include Anhui, Jiangsu, Shanxi, Shaanxi, Shandong and Henan. There is no Hubei. Let's go downstairs. Hubei said that the six provinces in the Central Plains were a complete joke. The Central Plains refers to the area north of Huaihe River and the historical and cultural dialect area. Zhuge Liang's example clearly shows that the north of Huaihe River is the Central Plains, and half of Jiangsu and Anhui are in the north of Huaihe River. Xuzhou, Jiangsu, the three countries claimed to be from the Central Plains. Hubei is all located in the south of Huaihe River. How can it be the northern Central Plains? Don't be ridiculous, everyone.
