After when? There is no test in historical records. The author found a reference data. China's first dictionary Shuo Wen Jie Zi was written by Xu Shen, an outstanding scholar and linguist in the Eastern Han Dynasty. He has read a lot of classic works and is proficient in textual exegesis. It took him 2 1 year to summarize the research results of pre-Qin and Han characters and compiled 9353 words. His "rhyme" department has collected a large number of uncommon words, but there is no rhyme. Xu Shen was born around 58 AD and died in 147 AD. He was 10 years old in the year when "gold came out of Hu Juan", which caused a sensation in the ruling and opposition circles. Even if he is young and unheard of, he should know that this great lake is not far from his hometown of Yancheng in Henan and Luoyang in Kyoto. It can be concluded that the word "Xun" was newly invented after Xu Shen. In other words, the name "Wuhu" that night was in the year of 147.
According to historical records, Ruan Yu, a writer at the end of the Han Dynasty, wrote a letter to Sun Quan on behalf of Cao Cao: "A few years ago, we built a new boat in Qiaocheng and even Jiujiang. You have to look at the shape of the lake and put people's ears on the river ..." The word "lake" in this article means lake. This letter was written about fifteen years before Jian 'an (2 10). The name of the lake is used for letters, so its name should have been issued a few years earlier.
The word "rhyme" was created by people because of the combination of "nest" and "rhyme". Its purpose is to distinguish it from the political name "nest" and the city name "cloud" and to take the abbreviation of place names in ancient books. Guo Pu, a writer in Jin Dynasty, and Hua Mu, a writer of Haifu, both wrote about lakes. When Shan Li, a scholar in the Tang Dynasty, commented on it, he meant that the lake lived in a bird's nest. Interpretation of Kangxi dictionary: Xun: the name of the lake. In Hefei County, Luzhou today. "The Chinese Dictionary explains:" Cloud is the name of the lake. This is today's Chaohu Lake. "
The pronunciation of the word "Xun" is also different from the political name "Chao" and the city name "Xun". According to Shan Li's notes on Selected Works, Li Xian's notes on the History of the Later Han Dynasty and Kangxi Dictionary, the initial reading is zāo (bitter sound), and the initial reading is Z (early sound).
2. Chaohu Lake-Rectifying its name. As the proper name of Chaohu Lake, "Chaohu Lake" was first used in the Three Kingdoms period. Ancient and modern scholars took Zhuge Liang's "Model" as the head, and "four trips to Chaohu Lake failed", which was founded in Shu for six years (228). I read a letter written by Ye Liu to Lu Su at the end of Han Dynasty, saying that Bao Zheng, a native of Lujiang, became a hero because of "more than 10,000 people in Chaohu Lake". This letter was written before the winter of the fourth year of Jian 'an (199) and came out 19 years earlier, so it should still be concerned.
In the Jin Dynasty, "Chaohu Lake" began to be widely used in contemporary literature and letters, and it officially entered the history books after the Southern and Northern Dynasties.
It should be reminded that the early pronunciation of "Chaohu" is different from that of "Chaocheng", and it is not pronounced as cháo (sound tide). Pei Songzhi, a scholar in the Southern Song Dynasty, made a special phonetic symbol in The History of the Three Kingdoms: "Chao, Yin is opposite". Pronounced as z m 4 o (early sound).
Why is this? Because Chaohu Lake's real name is Xunhu Lake, the nest sounds like Xunhu Lake. In the Tang Dynasty, Chaozhou and Jichao counties were built from generation to generation, and people abandoned complexity and simplified it. The name of the lake, the name of the government and the name of the city are integrated, and the name of the nest is universal. Therefore, the political name "Chao" is pronounced as cháo (Chao), and "Chaohu" is used instead of "Wuhu". This is clearly seen in historical documents. During the Wei, Jin, Southern and Northern Dynasties, "Wuhu" was widely used, but rarely after the Tang and Song Dynasties. The reason why Zi Tong Zhi Jian uses "Five Lakes" is because it is based on historical materials and respects the original appearance. After the Ming and Qing Dynasties, "Xunhu" generally only appeared in dictionaries to explain the history of Chaohu Lake and the sound and meaning of the word "Xunhu". This is also the historical basis for us to recognize "Chaohu Lake" as the proper name of Chaohu Lake.
