Because Guoye Village is on the dune slope on the northwest side where there is a yellow hibiscus forest, and yellow hibiscus tree is commonly called Guoye, hence the name.
This Guoye forest is evergreen.  In spring and summer, the yellow flowers flourish. The east of Guoye Village is facing the beach, and the connected sea and sky enable a very broad vision.  It is very famous and typical attraction to appreciate the sunrise. While here, you must first climb the Sunrise Observatory, because the Sunrise Observatory enables to look down from a height and provides the most suitable point of view to watch the sunrise especially if the weather is good, overlook the sea on the east, the red rising sun slowly rises from the sea in addition, as Penghu has no light pollution, the sky gradually changed from the original dark and gray to orange-red the golden sun rises from the sea level and the whole sea surface instantly glitters with bright orange luster against the golden sun due to the special erosion terrain on the beach, when the reflected sunlight is again reflected on erosion terrain. Because the erosion terrain is broken, the light reflected on the rock is like diamonds floating on the sea, glistering golden lights the whole sea is like warriors wearing golden tunic, marching forward along the golden sprays. It is really dazzling and beautiful. The Guoye sunrise shows a style completely different from Alishan sunrise. If the Alishan sunrise is like a pretty daughter of simple family wearing chiffon cloth, Guoye sunrise has the way of great generals! So Guoye Sunrise is one of the 8 famous old sceneries.
After watching the sunrise, you should note that if the weather is good enough with no cloud, you can also see the distance of Taiwan, with a vivid outline of the central mountain range you can also use a telescope as assistant to increase the watching pleasure!
In addition, I’d like remind that under the Sunrise Observatory there is very erosion terrain on the beach, but you’d better watch it only, because these stones are very slippery. For several times, I witnessed that tourists who cannot help being attracted by the beautiful sunrise want to take pictures on the stones. As a result, they all slipped down with feet in the air. However, the wave is rather fierce when the tide is coming, then do pay attention to safety and do not climb up the stones, or you may not only fall down, but also may be rushed away by the wave.
