Hangzhou was originally the money of Tang County and Qin Dynasty. Therefore, when I say the name Hangzhou, I say the name Qiantang first. There are three opinions about the name of Qiantang: First, the interpretation of "The Year of Spring Travel" says that those who were born in the Tang Dynasty had a Tao, so the one who took the Tao was Zhejiang. The land belongs to the Shu family. The ancient word "money" was named after it. When it comes to Han Shu and Jin Shu, it is said that "Wulin Mountain is the place where Wulin water comes from." Kan Qian said, "Wulin Mountain is full of spring water, and there is a sea of people in the east." The so-called Wulin water, the so-called spring water, is the water formed by the confluence of two streams in Lingyin today. During the Qin Dynasty, the West Lake was still one of the bays affected by tides. Residents built ponds to defend them, so they called them spring ponds. Wang Mang changed his name to Quanting County and changed only one word. In the Tang Dynasty, it avoided the taboo of the country, added soil as a pool and opened a pond. The seawall levee is located in the east of the county. The county advised Cao Hua to build this new pond to prevent seawater. At the beginning of fund-raising, there are some people who can make a difference, and Qian Qian. Within ten days, new people gathered. The pond is not finished and is no longer occupied. So the people who carried the earth and stone abandoned it and the pond became a success. Hence the name Qiantang. See money for this statement. Liu Daozhen said it in Liu Song. Its so-called money is coin money, not spring water. Liu Xiao in Shi Shuo Xin Yu also quoted Qian's words: "The counties are offshore and go with the flow. The surnames of counties collect money to hire people, and because they think they are names, they turn the soil into a pond. " This is still coin money, not a spring, but the builder is not Huaxin's ear. To sum up, the theory of "Chun You" must be well-founded, but there are doubts about its dependence. Huaxin and Hao's story seems to be very similar. But Qin Shihuang established a county named Quantang. Huaxin is a Han Chinese. Why did you add it later? Take the second statement as appropriate. It is common sense to cover people near rivers and seas and use soil to control water. There may be a pond under Lingyin Mountain. Don't wait for Huaxin to have a pond. The pond newly built in China is not at the foot of Lingyin Mountain. As for the name of Hangzhou, it began in Sui and ended in Yuhang. Yuhang is a county established by Qin Shihuang. There are two versions of its name: one is Yu Xia's eight-year southern tour, so it was named Yu Xing. Walker, the ark is also. Yu built a boat here and prepared to cross the river. The more people think about it and pass it on. After this mistake, I became a redundant person. According to legend, Yu Hang stayed here at Duhui, hence the name. According to the above two statements, it is called straight. It doesn't matter if you were Yuhang County in the Qin Dynasty, but it wasn't Yuhang County. But if Hangzhou is a boat, the two theories are the same. Hangzhou was located in Yuhang County in Sui Dynasty. The name of Hangzhou is taken from the county, which is the place to govern the state. Later, he moved to Zhou to govern Qiantang. After the Tang Dynasty, Qiantang became the name of Hangzhou.
