The QiYi Blossom Lock is part of the QiYi Kong Ming Lock series and presents a design in which the pieces seem to open like the petals of a flower once the correct order to disassemble it is located. That is precisely the small mental "click" that makes this model special: going from seeing a block to sensing the hidden movement that allows it to be separated.

The challenge is to separate all the pieces and then reassemble them until it is left as it was. There are no turns or hidden mechanisms: everything is solved with observation and some practice. Its difficulty sits at a medium level within the series, suitable for someone who has already faced some simple burr puzzle and wants something a bit more elaborate.

The manufacturing is the usual one in this QiYi line, with precision moulded plastic pieces, fits that adjust without annoying tolerances and a firm general feeling once assembled. The size is comfortable to handle with both hands and serves both to play occasionally and to leave on the table as a desk or side table object.

It fits well for those who already collect Kong Ming Lock pieces and want to add a different variant to the classic cubic locks, and also to give to someone with interest in traditional Chinese puzzles. It is a good intermediate step before jumping to the most demanding models of the series.

As a usage trick, when disassembling it, it is worth noting how the pieces "open" and not simply separate them without thinking. That observation is what later allows the assembly without going blind. With practice, the complete process can be done in a few minutes.
