Locks have a long history, almost at the same time as private ownership. According to the unearthed cultural relics research and historical records, the development of locks up to 5,000 years of history.

Initially, humans simply tied the door with a rope, and finally put a special knot on the opening, which is the earliest prototype of the lock. This tightly tied knot can only be opened with a tool made of animal or animal bones called "ī (xī)", which is the earliest key.


Wood latch

To the Yangshao period of 5000 years ago, our ancestors created a wooden lock installed on a wooden frame structure, which is what we call the latch, which is the oldest lock in the world and can be described as "the world A lock.
