The ability to think makes humans unique from animals. As an effective way to boost children’s brainpower, thinking exercises improve children’s logical reasoning and analytical skills, develop their decision-making abilities, and help children to perceive the world objectively. The Great Wall, a military defensive work that was being constructed over thousands of years, has been included in UNESCO’s World Heritage List. With the book, children will know how the Great Wall was built as well as more information such as the battles waged in and outside the Great Wall, the life of ancient Chinese people living in the garrison towns, and cultural exchanges between different ethnic groups and countries.

What weapons were used by soldiers on the Great Wall? What buildings were there in the garrison towns? What did foreigners do when they passed the Great Wall? Answers to all these questions are to be found there. The book delivers knowledge about the Great Wall through various brain games including mazes, puzzles, rule-finding games, number games, computational games, passcode games, space games, sudoku, observation activities, drawing activities, and memory games. In this way, the book seeks to boost children’s comprehension skills, focus, observation skills, computational thinking, symbolic thinking, reasoning skills, and analytical skills.
