Reducing the Chinese Diction:
Originally the Chinese had 10,000 words in its language over years of culture, religion and stories from generations. But when the Emperor came into power he soon reduced those to 3,000 thousand words completely throwing out all of the culture, religion and stories of the past.
This maybe only one down side but it is quite a big one, just think of all the things we could've learned about ancient China because of those words. But despite this down side it's up side is fairly positive. Decreasing the word count made the language easier to learn for other countries, making it easier would boost the population of China.
My conclusion about this is a 50/50 situation, the Emperor had a strong disregard for Chinese culture, but in doing so he made it easier for new comers to migrate to China and boost China's economy.
Was the Emperor a good Leader?
Despite all the useful things he has done over his reign, my opinion on this Emperor still stands.
Qin Shi Huang was a selfish, greedy Emperor which means he wasn't a good Leader.
You may argue that all of his achievements did something great for the Chinese economy such as the Great Wall of China with its great tourism attraction and capable defences, and yes I would agree the Great Wall of China was a great thing, but the Emperor didn't intend the great Wall of China to fend off armies, he just wanted to see the land that he conquered from high up. Another down fall was that over one million people died making this Wall. The emperor didn't make it for the people he made it for himself.
My favourite example of the Emperors self centred personality was the Terracotta Army which severed no purpose to anyone apart from the Emperor himself. The Terracotta Army in those days were a wast of money, resources and 37 years.
My conclusion is mainly based around the emperors selfishness, which are qualities of a bad leader. When you are leading a group you ask for people's opinions on the matter, and after you have heard all of them you choose the best one for the group or you come up with your own that combines everyone's.
