China's provinces are divided, and mountains, rivers, lakes and seas are the most natural dividing lines, which is a practice formed since ancient times. For example, between Hunan and Hubei is separated by Dongting Lake, one south and one north. For example, Shandong and Shanxi are separated by the Taihang Mountains and between Henan and Hebei, between the Yellow River. So, what is the "Guangzhou" between Guangdong and Guangxi? What is the special meaning of this word?

"Guangdong" is naturally not a mountain, river, lake and sea, so the division of Guangdong and Guangxi is particularly special. The area around Guangdong was originally called "Lingnan", which is the Lingnan of "three hundred lychees per day, and the Lingnan people who do not quit being Lingnanians" in Su Dongpo's poem. There is a big misunderstanding about Lingnan civilization, many people believe that Lingnan did not have its own civilization before Qin Shi Huang sent troops into Lingnan.
This is because, during the Xia, Shang, and Zhou dynasties, China's economic and political culture has always developed around the Yellow River Basin, which is regarded as the "Central Plains Land", and the South has not been fully understood, and at the same time, the Central Plains Dynasty likes to send prisoners to the "Town of Miasma" in the south, which makes people subconsciously feel that Lingnan is a barren land, quite terrible, and it is fearful to mention.
But later, Lingnan began to gradually become a "wide" land. This Guang, speaking of it, is related to the Qin Emperor and Han Wu. As we all know, during the reign of Qin Shi Huang, the Lingnan area was formally in full contact with the Central Plains, in 214 BC, the Qin army basically occupied all the Lingnan regions, and then Qin Shi Huang set up counties in the local area, most of today's Guangdong belongs to "Nanhai County", and Guangxi has partly belonged to "Guilin County".
The first administrative division in the history of Guangdong and Guangxi appeared. However, the Qin Dynasty fell too quickly, and when the Central Plains were in turmoil, the Qin general Zhao Tuo, who was originally stationed in Lingnan, gradually unified the Lingnan region and then established the State of South Vietnam. After the establishment of the Han Dynasty, the State of South Vietnam was incorporated into the territory of the Han Dynasty and became a vassal state, and once separated. After Emperor Wu of Han ascended the throne, he formally pacified South Vietnam.
Since South Vietnam had become part of the Han Dynasty, Emperor Wudi of han naturally had to take some trouble to appease the local people and govern properly. After 111 BC, Emperor Wu of han divided the state of Nanyue into 9 counties, sent Han Dynasty ministers to administer it in batches, and issued an important will: "At the beginning of the opening of Guangdong, it is advisable to spread the letter of grace." "Translating it means that the officials of Guangdong should pay attention to the widespread benevolence of the people.
"Guangxin" has a reference allusion to the name. Of the 9 counties that South Vietnam was divided into, one was called "Jiaotong", which was recorded in the Western Jin Dynasty King Fan's "Jiaoguang Chunqiu" (Jiaoguang Chunqiu) as follows: "Jiaozhou zhi wins Lou County, and Yuan Feng moved to Cangwu Guangxin County in the fifth year of the Yuan Dynasty. "YuanFeng is the era name of Emperor Wu of Han, that is, during the reign of Emperor Wu of Han, the center of governance of Jiaozhi County was located in Guangxin.
At the end of the Eastern Han Dynasty, the former "Jiaotong Thorn History Department" became "Jiaozhou", and the state administration was once again moved to Guangxin County, Cangwu County. During the Three Kingdoms period, Sun Quan of Eastern Wu ordered that the four counties of Jiaozhou (Nanhai, Cangwu, Yulin, and Gaoliang) be carved out and turned into a new state, named Guangzhou after the previous state administration "Guangxin". This is the origin of the word "Guang" in Guangdong and Guangxi, and its meaning refers to Guangxin. The two cantons are divided by Guangxin, guangdong in the east and Guangxi in the west.
