A large lake in Shanyin Island Gen County is considered to be naturally formed. Songjiang City, the county government, is at the source of this lake. The lower reaches of the lake have been connected to Izumo City. It is said that the lake here is a semi-salt water lake, the kind with bubbles, and there is a local specialty. Similar to our oysters, especially suitable for miso soup. After I went to Songjiang City to play well, I stayed for one night. I can see the scenery of the Yandao Lake from the hotel. The lake is really big. It is rare in such a city center. It is also considered one of Songjiang's tourist attractions. There is always a sightseeing boat to take. Unfortunately, I didn’t have time and didn’t see the sunset here. Maybe the sun was more beautiful when it was good. The first night I passed by was just dark. I didn’t see it. When I passed by the bridge on the lake at night, I saw many young men standing in the lake playing night fishing. The nightlife in the small place is also very good.
