Chaozhou West Lake, the mountains lean on the green lake, lake side mountain indigo. It used to be the moat of the ancient city of Chaozhou, commonly known as "trench pool". Today, with the center of urban construction moving westward, it has become a green watershed between the old and new urban areas, and also a link of the famous city Tenghui. In implementing the urban construction policy of "Protecting the ancient urban area and building the new urban area", both should take into account each other and advance side by side. If Chaozhou's urban construction planning has been positioned in the landscape gardening style, then the West Lake is a green lobe of the ancient urban area. It can be called the green pearl of the new century environmental protection city. In the past, the West Lake was a tributary of the Han River and a thin Lake washed up by the collapse of the embankment.
