The West Lake of Quanzhou is the last scene of my visit to Quanzhou with Xiangge. It was once called Duanjiahu Lake. It is located at the southern foot of Qingyuan Mountain. It is an important part of the northwest ocean flood discharge and drainage project. West Lake is located in a low-lying plain area. In the past, when large floods occurred, it relied mainly on natural water surface and paddy fields to release floods, commonly known as "Northwest Ocean".
