This is more than a toy; it’s an Artistic Masterpiece of Mortise & Tenon Craftsmanship. Featuring the uniquely Chinese 9-piece Geometric Cube, it offers an infinite, Tangram-like creative challenge. The set includes three eras of iconic trains—High-Speed, Electric, and Steam—alongside miniature models of the Great Wall and ancient Chinese bridges. The reliable M&T structure ensures durability and simplifies assembly, letting children focus purely on fun. It comes with Oxford University Bilingual Stories and rich educational content, meeting parents' demands for quality learning. A special Letter of Exploration is included to inspire the child’s imagination and a longing for poetry and distant dreams.
