Cliff is made up of cliff erosion and sea gulfs, sitting about a hundred metres above main sea level. Downwards from the observatory, slapping waves in the deep valley are thrilling and soul-stirring. It is said that in Qing Dynasty a fisherman's wife was kidnapped by mobsters to this island. Resisting, she escaped to this cliff, jumped off, and died. To commemorate her chastity, this cliff is named Suicide Cliff. A Thread of Sky Situated in the west cape of Heaven King Port () in Dongyin, is a cliff erosion. Along two sides of the meandering combat trenches are bristly banners. Setting foot at the observatory after a short walk, just to see the whole sea and sky are squeezed into the perpendicular gap between the rocks. Waves rush into the narrow chasm, taking away rock little by little, creating a marvel of nature. Four inscribed words on the cliff wall, 'Sky Cleft Hark Waves' was given by General Ming-Tang Lai. Andong Tunnel Next to the command post is Andong Tunnel, a massive construction project with uncanny workmanship. Inside the tunnels are fully equipped with bedrooms, an ammunition depot, Zhongshan room (), bathrooms and even a pigsty. Along the walls outside of the eight outlets of the tunnels is a gathering spot for Larus crassirostris (), which breed every spring and summer. Mountain Facing Guanyin At the foot of the east hill of Mt. Enai () and the west of Shaoziao (), the straight up huge stone is named Mountain Facing Guanyin (). From at sea, the stone looks like a cross-legged Guanyin, but it looks like a standing Guanyin facing the mountain, when seen from the mountains. It is documented in Dongyin chronicles that when the cloud-flying Putuo () Guanyin was hunting a goblin, it trailed to the island. Seeing the goblin run into the chasm and become trapped, Guanyin cast a spell and took the surrendered goblin back to the South China Sea. The statue is here for later generations to pay respect and ponder. Dongyin Distillery Dongyin Distillery () was founded in 1961 and has been the most important business on the island. Dongyin Distillery is on the same latitude, 26 N, as another three distilleries, Mao Tai, Luzhou Tequ Liquor () and Wuliangye Liquor (). The indispensable conditions to produce fine liquor are optimal humidity and temperature, microorganisms for fermentation, and spring water rich in maifanite
