We had another great double period class today. Amira shared photos with me of her trip to China with her former school in AZ. She visited the cities of Honzou and Shanghai. Amira recalls the intense pollution in China. I asked her if there was one particular outstanding site she visited there that was memorable and Amira said it was more the experiences with people and the W Hotel in Shanghai that were wonderful. It was too bad the group could not factor a trip to the Great Wall of China into their trip, so we learned about it today. The photos of the Wall along its 5,500 mile path in China are dramatic and beautiful. Amira was interested to see how wide the Wall is for people to walk atop it. She learned that it was built 2,300 years ago by Qin Dynasty to protect China from attack. The Wall crosses 9 Chinese provinces and runs over terrain such as the beach, desert and mountains. Nearly 1/3 of the Great Wall has disappeared without a trace. It is the only one of the 7 Great Wonders of the World that can be viewed from space with technological visual assistance.
