This is a set of toy sets themed around construction sites, including various engineering vehicles such as tower cranes, hoists, excavators, mixer trucks, and trucks, as well as related scene accessories. Children can play with these toys to simulate real construction scenes and experience the joy of engineering work in an immersive way.

During the process of simulating construction scenarios, children can fully exert their imagination and independently write and direct stories about engineering assignments. At the same time, operating different vehicles to complete "construction tasks" can exercise fine motor skills and logical thinking abilities of the hands.
