I believe many people know Luban Lock. In fact, it can also be folded using origami. The origami tutorial of Luban Lock is very simple, but some beginners still can’t understand it. This actual shot emphasizes the key parts, and I hope everyone can learn it.
One yuan is special, not a 2:1 ratio, but it also has its benefits. The tutorial is also posted for reference.
The following is a real shot using one yuan as an example to start.
Fold the long side in half.

BanknotesTurn over. The length of the short side of one yuan is 63mm and should not be divided into five equal parts. Because some of it needs to be collected inside, four equal parts are enough. Then measure the position of 13x4=52mm and divide it into four equal parts. The remaining 10mm is the part hidden inside.
