The QiYi Kong Ming Lock Fetch In The Cage is a plastic puzzle within the Chinese tradition of the "Kong Ming Lock", also known as Lu Ban locks. It is a family of mechanical puzzles based on interlocking pieces that must be disassembled and reassembled through a specific sequence of moves. Its origin dates back to ancient China and its name pays tribute to historical figures associated with engineering and strategy.

This particular version, known as Fetch In The Cage or Cage Extract, poses the challenge of extracting a piece trapped inside a cage without forcing the assembly. The solution does not depend on strength but on identifying the correct sequence of moves, something that requires patient observation and some trial and error until the way the pieces articulate is understood. It is a purely logical challenge that can take from a few minutes to several afternoons depending on the user.

QiYi MoFangGe brings this classic idea to a plastic format, with pieces designed to withstand continuous use without splintering or deforming. Unlike a magic cube, there is no need to memorise algorithms: the challenge is purely logical and spatial, and satisfaction comes when the internal mechanism is finally understood. Moulded plastic also makes it easier to reassemble the puzzle once disassembled, something that in traditional wooden versions can require more precision.

It is a puzzle suitable for teenagers and adults who enjoy wit puzzles and want something different from a speed cube. It also fits well as a gift or as a desk piece to work with the hands between tasks. Within the QiYi catalogue, it is part of the wit puzzles line, complementary to the well-known cubes range. It is a good way to approach the Chinese tradition of Kong Ming Lock without needing a handcrafted wooden model, and at a very reasonable price.
