After Qin Shihuang annexed six countries and unified China, he stepped up efforts to repair the equator, open waterways and inspect counties. Qin Shihuang toured the sea in the east. According to the law, Qi people went to Xianshan to find medicine. A few days later, people from Donglu returned to the Palace and reported that there was an island in the sea not far from Jieshi coast, which was dozens of miles away from Fiona Fang. The island is surrounded by water, full of green; Wild flowers are everywhere, dazzling. Especially the fine sand and golden light on the shore, walking on it is like stepping on a soft carpet. Hearing this, Qin Shihuang decided to lead troops and horses to ferry to visit the island.

As soon as the first emperor landed on the island, he could not help admiring: "I have traveled all over the world, but I have never seen such a wonderful landscape." Besides, it's calm here, the sand is soft and flat, and the ship is easy to sail. Where it enters the sea, it belongs to it! "So, the first emperor lived on the island all night, and only went to the sea to seek immortality that day.

The next day, Qin Shihuang ordered Lu Sheng and his disciples to go to the sea to look for the elixir of life.

Lu Sheng and his disciples have been drifting at sea for many days, without water or food. No fairy mountain was found, and no fairy medicine was found. They knew that if they came back empty-handed, they would commit the crime of deceiving the monarch and ask for 1000 yuan. In desperation, Lu Sheng came up with a plan. He made a spell with yellow satin, which said, "It was Hu Ye who died in the State of Qin", and then returned to the palace with his disciples. When I met the first queen, I lied that the immortal in fairy mountain told me to give it to Qin Shihuang at once.

When Qin Shihuang saw the "fairy book", he felt uneasy. How can he be a man looking for fairies? Busy rate of military forces to get back to Xianyang day and night. Then a large number of migrant workers were recruited and general Meng Tian was sent to build the Great Wall in Wan Li.

Later, people set up a monument on the rock on the island where Qin Shihuang stood, engraved with the words "Qin Huang's Land of Seeking Immortals and Entering the Sea". And this beautiful island, after vicissitudes of life, gradually connected with the land, people named it "Qinhuangdao".
