The Great Wall of China is a series of fortifications made of stone, brick, tamped earth, wood, and other materials, generally built along an east-to-west line across the historical northern borders of China in part to protect the Chinese Empire or its prototypical states against intrusions by various nomadic groups or military incursions by various warlike peoples or forces.

The Great Wall of China is a series of stone and earthen fortifications in China, built, rebuilt, and maintained between the 5th century BC and the 16th century to protect the northern borders of the Chinese Empire during the rule of successive dynasties.

This is a great website with loads of information on the Great Wall of China

I found this really helpful for note-taking, it also has all the bibliography already done for you at the bottom

Nearly everyone has heard of the huge, stone wall known as the Great Wall of China. The Great Wall of China was built mainly to protect the Chinese Empire from the Mongolians and other invaders. The Wall has been periodically rebuilt and modified throughout history by each reigning Chinese dynasty.

The Chinese worked on the Great Wall for over 1700 years. In turn, each emperor who came to power added pieces of the wall to protect their dynasties. But the wall was not a solid wall. It was a line of disconnected barricades.

I am not doing Kites but I was, this website has so much information on kites, I found it really helpful.

Kites may date back as far as 3000 years, where they were made from bamboo and silk in China. Exactly how or when a kite was first flown is a mystery, but one legend suggests that when a Chinese farmer tied a string to his hat to keep it from blowing away in a strong wind, the first kite was born.
