Both Changdao National Forest Park and Changdao National Nature Reserve are located on the islands, which were on a cross-Bohai Sea flyway. 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. == City honor ==
