The historical evolution of Tangram

1. 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. The Ming and Qing dynasties were widely circulated among the people. In Volume I of Leng Lu Miscellaneous Knowledge, Qing Lu Yi wrote, "There are seven ingenious maps recently, with five forms and seven numbers, and its changing forms are as many as a thousand. The body is small and changeable, and the tools of the game are enough to dispel boredom and break silence, so the secular people like it. "

2. In the 18th century, Tangram spread abroad. Needham said that it is one of the "oldest pastimes in the East", and up to now, the library of the University of Cambridge in the United Kingdom still has a collection of "Seven Clever Pieces of New Music". Edgar Allanport, an American writer, refined a jigsaw puzzle with ivory. French Napoleon also used jigsaw puzzle as a pastime in exile.

In the 3rd and 18th centuries, Tangram spread abroad, which immediately aroused great interest. Some foreigners played it all night and called it "Tangtu", which means "a jigsaw puzzle from China".
