It has always been an important frontier for border defense. A strategic place for military strategists. In the early Ming Dynasty, in order to prevent harassment by bandits, protective fences were set up at Jinding Seaside and forts were built at Yingbiao Mountain on Sanzao Island. In the mid-Ming Dynasty, a policy of seclusion was implemented.
