Above are one of the lock from the famous LongMing Lock Family.

Legend has it that LuBan, a famous carpenter from the Spring and Autumn period (upon a long time ago in China), intend to test his son’s intelligence, so he makes a toy out of 6 wooden sticks and ask his son to dissemble it. But it takes the boy a whole night to take apart the toy. (Even costing extra time for you to assemble that.)

This toy is what it was later called LuBan Lock, but that is just a legend. LuBan Lock, also known as Kongming lock, the Six Interlocking Blocks, No Way Out and Trouble Blocks etc , actually derive its name from the tenon structure originating in ancient Chinese architecture.

This 3-dimensional assembling toy is interlocked by fitting concave and convex parts together and the structure is very intricate. It comes in a variety of types and shapes with different internal structures, but one thing they have in common is that they are all easy to disassemble but difficult to assemble. in trying to piece together the toy, you need to pay a careful observation and analyze its internal structure.

Also if you want to try your boy’s brainpower, here is some of the items you can get from here:

It has only 3 sticks and may seem a piece of cake. But it should turn out to be much more difficult than meet the eyes. you have every reason to be proud of your boy if he manage to assemble it in the end. Maybe your boy is just a genius who can solve the puzzle in just a few minutes and get bored. Now it will be father’s duty to relieve the son’s boredom, so get a more challenging one here:

So this is not a toy at all, this is also a great gift to inspire your child’s intelligence.
