Mortise and Tenon Structure Luban Lock
Luban Lock, also known as Kongming Lock, originates from the mortise and tenon structure in ancient Chinese architecture. It uses no nails or ropes, relying entirely on its own structural connection for support, demonstrating the philosophical idea of 'harmony between man and nature'. Its internal structure is intricate, easy to take apart but difficult to reassemble, making it an excellent tool for exercising spatial imagination and logical thinking.
