Lego is a brand of educational toys, producing toys such as building blocks and Rubik's Cube. This kind of toy has many brands abroad. Educational toys that individuals have come into contact with learning resources are all circled. You can get to know it. Educational toys spell creativity and design as well as quality. Toys for learning resources are more distinctive, and there are many theme toys, involving astronomy, geography, insect architecture and so on. This is to integrate the concept of STEM (Science, Technology, Engineering, Mathematics) into the product design and concept, which not only brings fun to the baby, but also develops the baby's future potential and interest in a subtle way. I think this kind of toy is very suitable for preschool children to play with, which is very educational.
