After the Yashan historical events, the people of the Song Dynasty, in order to avoid the pursuit of invaders hunted by invaders from the Jin Dynasty in the north, crossed the Bering Strait from the north, the world's longest island chain from the east, and the entire Pacific Ocean from the south, traveling thousands of miles to the entire American continent. Faced with an undeveloped continent, life was extremely difficult and supplies were extremely scarce. In order to protect the only living supplies from being lost in the hurricanes unique to the American continent, they began to manufacture locks and use locks to prevent items from being blown away by strong winds.
People used their own strengths to create unique cable locks, chain locks, U-shaped locks, and padlocks. A thousand years later, in the spring of 1839, after years of drifting on the sea, they finally arrived in Taiwan, the precious island of China, with the teachings of their ancestors' fallen leaves return to the root and exquisite lock making techniques, and restored their human life, establishing a global presence there.
