Legend has it that during the period of Wu Zetian, Xue Gang enjoyed the lanterns and killed the second prince, Li Qi. After the catastrophic collapse, he fled everywhere and came to Jiuyan Mountain in Tiantai Mountain. He saw strange peaks and strange mountains, which were spectacular and wide, which was the advantage of military garrison. At that time, there was a man and a woman on Tiantai Mountain opposite Jiuyan Mountain. Soon after they got married, because they were dissatisfied with the tyranny of Wu Zetian, the man went to Jiuyan Mountain as a soldier. Every once in a while, women will walk from Tiantai Mountain to Jiuyan Mountain to visit their husbands. Over time, they walked out of a path connecting Tiantai Mountain and Jiuyan Mountain. Quiet days are short. When Wu Zetian heard Xue Gang's anti-Tang movement, she flew into a rage and ordered Wu Sansi to surround Jiuyan Mountain and implement a blockade policy.

From then on, a woman can no longer meet her husband. She can only overlook Jiuyan Mountain on Tiantai Mountain to express her love for her. This love for lovesickness has turned into a thousand years of gazing at Jiuyan Mountain on Wang Fu Cliff, and her tears flowing all the year round have also turned that path into love. Women's tears have cast a valley of love and a spring of tears in it.
