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, which can be embedded in bumps. There are more than 1300 shapes, and each shape has 12 different colors, mainly red, yellow, blue, white and green.

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

The origin of Lego:

The inventor of Lego bricks is Mr. Christensen, who was born in Filzgov village near Billon in 189 1. He has superb carpentry skills and was keen on making all kinds of small toys when he was young.

Small planes, cars and small animals from his hands 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" finally became all the rage. 1934, he designed the "Lego" trademark for his building block toys.
