According to legend, Kongmingsuo was a toy invented by Zhu Gekongming in the Three Kingdoms period according to the principle of Eight Diagrams Metaphysics, which was once widely circulated among the people. People pay more and more attention to it, which is conducive to relaxing body and mind, developing brain and flexible fingers. It is a leisure toy suitable for all ages. Kongmingsuo seems simple, but the mystery inside is endless, and it is difficult to complete the splicing.

Another legend says that in the Spring and Autumn Period, Lu's craftsman Lu Ban made a detachable toy out of six pieces of wood and told his son to take it apart.

After a busy night, my son finally opened it. This kind of toy is called Luban Lock, but it's actually just a legend. It originated from the tenon-mortise structure in ancient buildings in China. Therefore, Kongmingsuo is also called Lubansuo.
