The Qin Dynasty's form of government, Legalism, had a successful military and had laws which kept the city controlled.

Military:
The military of the Qin Dynasty had great success during the Warring States Period. They weren't afraid of expanding their borders while the other states were, which gave them more resources. Their weapons were effective and gave them their victory. They used the first ever crossbow, and fired iron arrows called bolts. This weapon was a lot more effective in their battles and during the Warring States Period (Keller) .
Legalism:
The form of government used by the Qin Dynasty was Legalism, and it was used because of its ability to have control over the state. The beliefs of Legalism were that humans were selfish, and wouldn't do something for someone else unless forced to. Also, if someone had hatred for someone else, they would likely just kill them. For people to not kill other people, they had to create Legalism. Legalism includes harsh laws and harsh punishments. This way, it makes it easier to control without too many disasters (Mark). 
Laws:
The laws helped emperor Shi Huangdi keep his city in order. One law is "if you see another person breaking the law, you must report them. Otherwise you will be quartered or beheaded." This way not too many criminals or lawbreakers can get away easily. If people broke the law, they would be punished or be charged a heavy fine. Another law was that "literature was denied to the population, except for restricted government officials." The emperor thought that controlling stupid people would be easier, since they couldn't doubt his leadership (Mark)

The currency that emperor Shi Huangdi innovated was called Ban Liang Qian. It was bronze with a square hole in the middle of it. Liang was a unit for weight and the coin weighed half of it. The name even means "half liang money" The square in the middle represented square earth and the circular part represented the sky. The circular part also represented the heavenly commandment while the square represents the authority of the emperor. Both represent flexibility, mobility, and stability. They were even material economical since the squares were easily made ("Qin and Han Money - Ban Liang Qian & Wu Zhu Qian").

Writing:
Qin standardized the style writing used throughout China. He required the characters to be uniform around China. Qin created two types of writing, one still used today. The first type writing was Small Seal. It was similar to Great Seal, except it was longer while the Great Seal was more round. Cursive was the other type of writing. It was a fluid style with connected brush strokes. The lines and letters are connected together. These characters do not look like characters in other styles. Cursive is valued for how it looks, because it requires the ability of the to create art with characters, rather than creating text only (Thomas).
The Canal

Qin used canals to have an easy and efficient way to transport items and people. At first, Qin had to use carriages for his troops and they started to run out of grain. The Qin troops could find barely any food. This was before canals were built. After it was built, large numbers of immigrants could be moved easily, and improved the economy of this civilization (Li).
