From the primitive use of rope knots to the contemporary new technologies of sound, light, and electronic control, the book collects various locks used in different times and places, classifying them into three main categories based on their invention and improvement processes: wooden, metal, and electronic. It extensively gathers and compiles them, accompanied by over 300 illustrations to demonstrate their design features, structural styles, operating methods, and working principles.
