Suchen lies about fifteen kilometers to the southeast of Lianyungang and is said to have been built under the order of Emperor Li Shimin (599-649) of the Tang Dynasty when he made an expedition to east China. The town lies on a small plain surrounded by mountains which are peppered with waterfalls, ancient trees and strangely shaped peaks. There is also a reservoir at the base of the mountains. Among the famous attractions in Suchen are Baojia Mountain, Boat Hill Cascade, Rock Gate, Crouching Dragon Pine, Immortal Cave and Jingang Rock.
Baojia Mountain is located in the southeast of Suchen Reservoir and got its name from a legend that a Tang Dynasty emperor was once besieged here. Fortunately his bodyguards reached him in time and were able to rescue him. So the emperor gave the mountain the name Baojia, which means "escorting the emperor". On top of the mountain there is the Siwang Pavilion, where tourists can get a bird's eye view of Suchen's beautiful landscape.
There are many caves but the largest is Immortal Cave, located on Donglei Mountain. The cave is about three to four meters deep and seven meters long. It can hold nearly ten people at the same time.
Jingang Rock lies to the west of Immortal Cave. It is a huge rock that has a pine standing at its top, like a tower of strength.
