Actually he ruled for 15 years but it was a good thing that he got rid of Feudalism.
I think we all believe in an immortal life ... after life that is.

i feel you my nigga cause he was a legalist and he was very selfish

but still, he had some contributions:
the unification of China. Qin Shi Huang wanted to avoid the recurrence of the political chaos of the Warring States Period. Thus, he abolished feudal system. Feudalism is the system in which the King ruled only the capital and its surrounding areas. He established the totalitarian rule. He divided his empire into 36 Provinces. Each Province was in the hands of governors – run by a civilian governor, assisted by a military governor – and an inspector is posted to each commandery and he is in-charged of informing the central governor about the local implementation of central policy and governor’s exercise of power. Governors are dismissed at will of the ruler. Qin Shi Huang also ordered the former royal family of the conquered states to move to Xiangyang, the capital of Qin, so that they will be kept under tight surveillance of rebellious activities.
He also extended roads and canals connecting the provinces to accelerate trade between them as well as to accelerate military marches to revolting provinces.
Qin Shi Huang united China economically by standardizing China’s units of measurements such as weights and measures and the currency.
