Introduction to Tiaohai Mingzhen: Qin Shihuang was furious when he learned that Meng Jiangnu had cried down the Great Wall, but he was attracted by her beauty and wanted Meng Jiangnu to be his concubine. Meng Jiangnu said: "If you want me to be your concubine, you must first do three things: first, build a long bridge, ten miles long and ten miles wide; second, build a tomb on a mountain ten miles square; third, wear sackcloth and go to the tomb in Long Live." Memorial." Qin Shi Huang agreed after thinking about it. In a few days, all the tombs of the Long Bridge were built. Qin Shihuang, dressed in sackcloth, set off in a row, crossed the Great Wall and went to the Long Bridge, and then came to the tomb to offer sacrifices. After the sacrifice, Qin Shihuang asked Meng Jiangnu to follow him back to the palace. Meng Jiangnv sneered and said: "You are stupid and cruel, you have ruined the people of the world, and now you have killed my husband. How can I be a concubine? Stop dreaming!" After saying that, she embraced her husband's body and jumped into the rough sea. For a time, the waves rolled, emptying and hitting the shore, as if they were lamenting for Meng Jiangnu.
