Introduction to Lego:

Lego bricks are children's favorite toys. This plastic building block has bumps at one end and holes at the other end that can be embedded with bumps. There are more than 1,3 shapes, and each shape has 12 different colors, mainly red, yellow, blue, white and green.

It is called "magic plastic building block" because it relies on children's hands and brains, and it can spell out endless shapes, which makes people fondle it. The hometown of Lego bricks is in Billon, Denmark.

Origin of Lego:

The inventor of Lego building blocks is Mr. Christensen, who was born in 1891 in Goff Village, Fils, near Billon. He has a superb carpenter's skill and was keen on making all kinds of small toys when he was young.

The small planes, cars and animals made by him are all lifelike. Although he doesn't know how to do business and his toys are often unsalable, it doesn't make him give up his hobby. Later, his spelling toy "Yoyo" was finally all the rage. In 1934, he designed the "Lego" trademark for his building blocks.
