Lego was founded in Denmark with a history of 65 years, which can be traced back to its gold-lettered signboard Lego. The trademark "Lego" has been used since 1934. Its language comes from the Danish word "LEg GOdt", which means "play well". This name soon became synonymous with high-quality toys produced by Lego, a toy factory in Babylon. Over the years, the "Lego" icon has also changed in many forms. The latest icon is made by 1998, which is slightly adjusted on the basis of 1973 version to make it easier to spread and identify in the media.

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