The Yangqin Lock Puzzle is a three-bar metal take-apart puzzle from Tea-Sip, based on a lock design that Chinese tradition traces to the Tang Dynasty. Three interlocking metal bars, cut with precise notches and grooves, form a compact 3D maze. The challenge runs both ways: work out the sequence that frees the bars, then rebuild the lock from scratch.

How It Plays
The known solving line starts with your left hand: hold the bar with the groove completely still. Your right hand pulls the other two bars toward the top-right corner, then guides them down, through the groove below, and pushes upward at exactly the right moment before continuing along the path. Timing that upward push is where most solvers stall. The bars feel locked, so people start forcing them, which only wedges the notches tighter.
The aha moment arrives when you stop treating it as a strength problem. Once the grooves align, the two moving bars slide free with almost no resistance, and the mechanism suddenly makes sense. Reassembly is the second test: running the sequence in reverse proves you understood the lock rather than stumbled through it.
Who It’s For
This is a desk puzzle for people who like mechanical, sequence-based challenges: metal puzzle collectors, engineers and programmers who fidget while they think, and anyone drawn to the story of a toy that legend says delighted Yang Guifei and stumped a young Cao Cao. As a gift it fits a stocking or a coat pocket, needs no batteries, and stays quiet enough for an office desk, which is why Tea-Sip shelves it with its decompression toys.
FAQ
How long does it take to solve?
There is no fixed time. Progress depends on spotting that one bar must stay still while the other two travel. Because the solution is a specific sequence rather than trial-and-error, the breakthrough tends to come all at once.
What if I get stuck?
Return to the known sequence: hold the grooved bar motionless in your left hand, move the other two to the top-right corner, then down and through the lower groove. If a move needs force, it is the wrong move; back up one step and change the angle.
Can it be reset and replayed?
Yes. Reassembling the lock is the built-in second challenge, and the durable metal bars stand up to repeated solving. Once you have mastered both directions, hand it to a friend and watch them wrestle the same three bars.
How much does it cost?
The Yangqin Lock Puzzle sells for $12.66 at Tea-Sip, complete in itself: three metal bars, the sequence hidden inside them, no batteries, no loose parts.

I’m not a hardcore puzzler, but the Yangqin Lock caught my attention due to its simplicity and complexity at the same time. It’s fun to play with, though sometimes I get stuck. The metal feels nice, and it’s a great way to unwind after a long day. Not too difficult for beginners but challenging enough to keep you engaged.
