The development and importance of ordinary locks to smart locks

When it comes to locks, the first thing that comes to mind is the gate lock. Whether the lock is a physical lock or a virtual lock, its main purpose is to protect property.

Locks were born almost simultaneously with private ownership. As early as 3000 BC in the Yangshao cultural site in China, wooden locks were installed on wooden frame structures. In the Eastern Han Dynasty, the technology of Chinese iron triple reeds has reached a fairly high level. Before and after the three-spring lock was used for more than 1,000 years.

In the primitive period, people lived a burrowing life. Although human society was in the initial stage of enlightenment, sometimes the primitive people still pushed huge stones to block the entrance. This should be the earliest form of the door. At the time, the object of protection was not a thief but a beast.

After the emergence of the private ownership system, the thieves followed, and the lock was officially born. As far back as 3,000 years ago, China already had the concept of lock.

"Word lock.
