Tung Ping Chau is an offshore island located in the northeast corner of Hong Kong in Mirs Bay and is close to the border with Guangdong Province in mainland China. Tung Ping Chau is unique in the fact that it is the only sizable island in Hong Kong made up of sedimentary rock. It is also home to some spectacular cliffs and wave-cut platforms. Landforms such as these are very rarely found in the rest of Hong Kong
