Shantou City has a history of 130 years. It used to be a rough bay, but it was only because of the alluvial sediment carried by the Han River in recent hundreds of years that it floated up from the bottom of a friend's sea. In the Yuan Dynasty, a large fishing village was initially formed in the present photochemical department area, which was called "Xia Ling" in the second year of Hongwu in Ming Dynasty (1369), and the Yuqian household in Pengzhou was located here. In the third year of Wanli in the Ming Dynasty (AD 1575), the sand ridges at the mouth of the Han River had accumulated into pieces, which was called "Shaxianping" in history. In the fifty-sixth year of Emperor Kangxi of Qing Dynasty (A.D. 17 17), a smoke pier and a battery were built here, which was called "Shaxian Head". From Yongzheng (AD 1730) to Qianlong, more and more people moved here to live. In addition to fishing and farming, they also use seawater to dry salt, and salt vendors from all over the world often come here to sell salt. The Qing government set up a station here to collect salt tax. Shantou for short. There is another "fish island" in Shantou. Later, with the increasing frequency of merchant ships in the past, the Qing government set up a "constant customs" in Fangji Mountain (now Cocoon Island) in the 21st year of Qianlong (AD 1756) to collect the customs duties of commercial transportation between the north and the south, which was the earliest customs in Shantou.
