When did ancient Chinese door locks come into being and what were they made of?

The earliest locks in China appeared in the Yangshao cultural sites in ancient times.

Ancient door locks were originally made of animal bones, ropes, and wood, and later evolved into bronze and metallic iron.

Locks are one of human inventions and have a long history, which can be traced back to ancient times.

At that time, productivity was low, and humans relied on hunting for a living, and their residences were mostly caves or simple thatched houses.

After primitive people took back the food they hunted or grew themselves into their homes, they invented locks in order to avoid being stolen by wild beasts and to protect their bodies from being infringed by wild beasts.

This is the earliest lock recorded in history, which can be confirmed from the Yangshao Cultural Site 5,000 years ago. The locks at that time were mainly wooden locks.

After arriving in class society, private ownership was established, and the role of locks gradually evolved into protecting private property from infringement.

In addition, the materials used to make locks have also changed, from animal bones, ropes, and wood to bronze.

For example, bronze locks appeared in the Western Zhou Dynasty.

With the development of productivity, human history entered the Iron Age, and the technology of making locks was further improved and optimized.

By the Eastern Han Dynasty, humans had invented metal locks, and their structures were more complex and ingenious, reflecting the level of science and technology at that time.

At present, locks have a newer meaning. The meaning of locks is not only reflected in physical locks, but also in virtual substances. For example, there are now electronic locks, password locks, electronically controlled locks and other types.

Locks play an important role in protecting personal safety, preventing property theft, regulating people's behavior, and maintaining social stability. Human beings will inevitably make locks with more powerful functions and more ingenious designs.
