Feng Zikai, who used to be a cartoonist, praised "Twelve Twelve Pieces", which is "on top of super-flat toys and rivals chess and Go", is a kind of puzzle game that can change according to one's inclinations.
According to legend, it is a domino whose ancestor is China, so it is still called "Pandomino bone marrow" abroad. "Shao Pamino" means that five pieces are connected, because although the twelve jigsaw puzzles have different shapes, each piece occupies the same number of squares, which is five, hence the name.
In the 1940s, the "twelve nerve-wracking blocks" were favored by western mathematicians, and they vigorously advocated it, and became popular all over the world for a while. In the early 1950s, Mr. Fang Bupu, a Chinese teacher at Yixin Middle School in Shanghai, my country, transformed the popular two-dimensional "brain-wrenching twelve yuan" into a three-dimensional one, making the "twelve yuan" more heart-wrenching and more charming.
