It is also called Hu Bao, perhaps because the waterway is long and narrow, but not as wide as the West Lake, so it is called Slender West Lake. The origin of this slender West Lake is also very interesting. Three salt merchants were talking and laughing on the lake and gave it many names, but none of them sounded good. A scholar heard it. He said that this lake in Yangzhou can be compared with the West Lake in Hangzhou, but it is not as wide as the West Lake, but it has obviously lost weight, so it has become a slender West Lake.
