Great Wall of China

The Great Wall of China os started in 220 BCE by Shi Huangdi with over one million workers, but only 3/4 of the people survived. The people who were working on it who died were buried inside of the wall to help support it and make it stronger. IT was built to defend the Qin dynasty from any invaders who wanted to end it because almost everybody hated them especially the people of the Qin. After the Qin, the people of the Han extended the wall to the Gobi Desert. The Ming Dynasty makes the wall a lot stronger to fend off even tougher enemies.
