The Changshan Islands, also known as the Temple Islands or Miaodao Archipelago are an archipelago of 32 islands located across the southern portion of the Bohai Strait, the waterway connecting the Bohai Sea to the Yellow Sea, collectively named after the two largest islands. In Chinese, they are also known as the "Long Islands", and anciently as the "Sandy Gate Islands" .
The islands are located between Jiaodong and Liaodong Peninsula, at the confluence of the Yellow Sea and Bohai Sea. They face Yantai in the south, Dalian in the north, Beijing and Tianjin in the west, and South Korea and Japan across the Yellow Sea in the east.
There are 32 islands in the Changshan Islands, 10 of them have permanent residential settlements. These islands were mostly formed by Proterozoic low-grade metamorphic rocks, with smaller amounts of Tertiary igneous rocks and Quaternary sedimentary rocks.

Temple Island got its name from the large number of temples that were built there. Xianying Palace is a temple that was built during the Northern Song dynasty, starting in 1122. It was originally a Taoist temple to the sea goddess Matsu, but became Buddhist later. At the present time the local government has restored the temple to its Ming dynasty appearance, although many additions had been made during the Qing.
Changdao Island was previously closed to non-Chinese nationals. Foreigners found on the island were swiftly taken to the passenger ferry terminal and placed on the next ferry back to Penglai by the islands police service. Islanders promptly reported all "outsiders" to the islands police service. Police explained the reasons for this was due to the high number of military installations on the Island. The Changdao Islands are now open to non-Chinese nationals. This was agreed by the local and national governments as of 1 December 2008.[4]
