Analysis:
According to the records about the origin of the thunder pool, the thunder pool is located in Lei Chi Township, Wangjiang County, on the north bank of the middle and lower reaches of the Yangtze River, and is formed by the accumulation of thunder water. Leishuiyuan comes from Huangmei County, Hubei Province, enters the lake via Susong, and flows 15 miles southeast of Wangjiang County, hence the name Lei Chi. Because the Yangtze River waterway from Jiujiang to Nanjing is also the throat of Huangmei, Susong and Taihu River inland shipping, the situation is dangerous, so it is a battleground for military strategists in past dynasties.
But it is not because of these that future generations can truly remember the thunder pool, but because of the phrase "dare not cross the thunder pool" that has been circulated for thousands of years.
In the second year of Xianhe in the Eastern Jin Dynasty (AD 327), the Soviet army rebelled in Liyang (Hexian County, Anhui Province) and mobilized troops to invade Jiankang (Nanjing). Jiangzhou secretariat wenqiao wanted to lead troops eastward. The secretariat made Yu Liang take advantage of Jingzhou secretariat Tao Kan, and said in the Message Bridge Book: "I am worried about the Western Expedition, too worried, and never crossed the line.
Therefore, Lei Chi has been recorded in the history books, and "Lei Chi one step away" has become a familiar idiom for later generations.
