The abbreviation of Hainan is Qiong, which comes from Qiongshan County.
During the Tang Dynasty, the imperial court established 5 prefectures, including Yazhou, Danzhou, Zhenzhou, Wan'an Prefecture, and Qiongzhou, and 22 counties, all under the jurisdiction of Lingnan Road. Qiongzhou, established in Hainan by the Tang Dynasty, is closely related to the abbreviation of Hainan today. Through the original meaning of the word "Qiong", we know that this word is very beautiful. Because there was a mountain in Qiongzhou at that time called Qiongshan. According to historical records, the soil and rocks in Qiongshan are white, jade-like and moist, and people have the urge to marry a jadeite after seeing it, so they named it Qiongshan.
At the beginning, Qiongzhou’s jurisdiction could only be one of the five states in Hainan Island, and its jurisdiction area was only one-fifth of Hainan. However, later Qiongzhou’s jurisdiction became larger and larger. During the Ming Dynasty, Zhu Yuanzhang made Qianning Tusi the prefecture of Qiongzhou, which governed 13 counties in Danzhou, Yazhou and Wanzhou, and transferred the South China Sea Islands to the jurisdiction of Yazhou. The Qing Dynasty basically followed the Ming system. In this way, in a certain respect, Qiongzhou has become synonymous with Hainan. During the Republic of China, the name Hainan began to appear, and the Hainan Special Administrative Region was established.
