Tianyahaijiao is located about 26km west of Sanya at Maling Shan. The beach here is peppered with rounded water worn boulders. Two large boulders, about 20m-high and over 60m-long, have the characters ,meaning "edge of the sky, rim of the sea," carved into them. This site is of special significance to Chinese tourists because this was once considered the end of the known world. Many melancholic poems have been written by disgraced officials, with one official decrying that it would take a bird six months to fly here. Many couples often say some lovely chat like "I will follow you to Tian-Ya-Hai-Jiao", which means they will never be parted and always be at each other's feet. Therefore, many newlyweds would pay a visit here in memory of their love. Now, it is one of the national AAAA level scenic spots and has become the symbol of Hainan and Sanya tourism.
The most popular scenic spot here is The Five Famous Stones, namely the love stone, the wealth stone, the health stone, the lucky stone and the progress stone. Each of them has a Chinese legendry, among which the most famous one is the love stone. It has the shape of "heart"and overlapped each other. Later people engraved "sun"and "moon" on the stone to symbolize forever love. When people say "I will love until the sea dries and the rock rots", it is the sea and the stone in Tianyahaijiao they referred to.
