Origin: Denmark "LEGO", as the brand of LEGO, is a synthesis of the Danish word "leg godt", which means "have a good time". In Latin, this word means "I put them together" (I built them). Lego uses "play" as the self-expression of the brand, similar to "Lego"

By 20 19, Lego has 2 million members all over the world, and Fortune once rated Lego as "toy of the century". Who would have thought that when the prototype of Lego was born in 1932, it was just one of the commodities-a wooden toy built by Danish carpenter Ole Kirk Christiansen in a small village in Bilund.

Two years later, Lego had its own name "Lego". 1949, Lego began to produce plastic building blocks toys, which laid the basic form of Lego toys, but the real toy revolution did not happen until 1955.

That year, Lego first put forward the slogan of "playing with learning" and advocated a new concept of both learning and playing. 1958, Lego changed bricks into sockets, which became another milestone in Lego's history. Since then, Lego has made great progress in acceleration.
