Knowledge expansion:

Tangram is an ancient traditional intellectual toy in China. As the name implies, it consists of seven boards. These seven boards can be combined into many figures (1600), such as triangles, parallelograms, irregular polygons, etc. Players can also combine them into various characters, images, animals, bridges, houses, towers, etc., or some Chinese and English letters.

Tangram was invented by the working people in ancient China, and its history can be traced back to at least the first century BC, and it was basically finalized in the Ming Dynasty. Ming and Qing Dynasties were widely circulated among the people in China. In Volume 1 of Miscellaneous Knowledge in a Cold Room, Lu Qing wrote: Recently, there are seven ingenious maps with five shapes and seven numbers, with as many as 1,000 variations.

Things are small in shape, changing at will, and full of games, which are enough to relieve boredom and break the silence, so secular people like them. /kloc-in the 0/8th century, the jigsaw puzzle spread abroad. Needham said it was one of the oldest pastimes in the East, and the library of Cambridge University in England also collected "seven ingenious new music".
