The logo as a whole symbolizes the Structure of Penghu. There is a lake inside the island, therefore outside the lake we see passionate waves while inside the lake water is as peaceful as a mirror. Also in the county, there is a famous big bridge across the ocean and five lighthouses named: Donji, Siyu, Mudouyu, Chamuyu, Huaui. All these five lighthouses stand firmly in the Taiwan straits and shine with splendor to show the spirit and characteristics of Penghu.
