Defense of the Great Wall
The Qin army invented new weapons to show their happiness for the new wall. The crossbow was the most deadly of the weapons it could hurl an arrow 250 yards with great accuracy. Another weapon they invented was the double edged iron sword this was an iron acasting technique. The soft bronze sword is no match for the double edged sword that the Qin dynasty invented. Another one of the Qin weapons is the bronze dagger axe; this weapon was made of jade, bronze or iron and had a metal spear at the point. Furthermore, the Qin dynasty was not the only dynasty with defensive weapons; the Han had many as well. One of the great Han weapons was the iron spear and is a melee weapon and can only be used in combat. Another one of the Hans weapons is the halberd this has a point at the tip and has a blade mounted on the shaft.
Communications of the Great Wall
Messages could be sent at amazing speeds along the ramports from one end of the empire to the other. Every 15 to 30 miles, beacon towers were built. They sent messages to one another using smoke signals by day and torches by night. One column of smoke meant a potencial attack of less than 500, two columns of smoke ment an potential attack of less than 3000, and four columns meant an attack with a force up to 10,000. This smoke technique that they used is called "Langyan". These beacon towers were also used for for soldiers to stand guard and be in control of these smoke signals.
Environmental and Habitat Problems
Some of the environmental problems that China had was because of the way some of the dynasties constructed the bricks. For example, the Han dynasty had a technique of building there bricks of packed earth. Therefore, this made more of the Hans area of the wall to be more unstable and make there section more likely to collapse. This may also lead to a possible break downs for the wall. As well as some of the sand storms could make some of the wall fall down. These are all things that can make the wall unstable.
