Many of our textbooks and books, in order to promote the ancient civilizations of the motherland, say that the only thing Earth can see on the moon by astronauts is the Great Wall of China. As a result, almost every Chinese who attended school, including teachers, accepted this understanding and never challenged it. However, this statement has caused great controversy among a group of elementary school students in the United States.
