The ends of the earth have their own places, in Hainan Island at the southern tip of our country. It is said that Su Dongpo, a writer in the Northern Song Dynasty, was exiled to the remote Hainan Island because he violated the interests of the reformists at that time. In those days, he was depressed and often went for a walk by the sea. One day, while he was walking, he was caught in a storm. He quickly hid under a boulder, only to see the waves surging on the sea. After a while, the wind stopped raining, the weather turned fine, the sea was sparkling and decorated with white sails, which was particularly beautiful. The poet was infected and his poems were full of enthusiasm. He wrote six characters "Tianya" and "Broad Sky" on this big stone. Later, a stonemason discovered Su Dongpo's handwriting and carved it down. Since then, people have called this place "Tianya" and this big stone is also called "Tianya Stone". Also, because it was originally called Jiaoling, and it is very close to the seaside, people combined Tianya and Jiaoling and gave a new name "Tianya Haijiao".
