evidence: Penghu National Scenic Area - Penghu Visitor Center [...] All of the islands in Penghu have a similar terrain, and most of them are flat. Clear seawater, pure beaches and beautiful skies make Penghu a favorite ocean resort area. Both Kuroshio tributary current (during summer) and Mainland China's coastal current (during winter) pass through the Penghu sea territory. Because of this the marine life in this area is very rich, making Penghu an outstanding classroom for marine biology. [...] Penghu shows its uniqueness in its cultural resources, thanks to the influences of its environment as well as Chinese culture and history. Many religious activities take place in Penghu; among 97 villages and towns in the islands, there are 183 temples. The ones with the longest history include the Tianhou, Wusheng, City God, Bao-an Temples, and the Guanyin Pavilion. There are also many important sites with great historical value.
