Mainly because the Qin Dynasty was too short, Ying Zheng became the King of Qin at the age of 13, achieved reunification at the age of 39 and died at the age of 49. As the founding father of the Han Dynasty, Liu Bang gives people a very young feeling. In fact, Liu Bei was 54 years old when he founded the Han Dynasty.

Qin Shihuang is three years older than Liu Bang, which means that it is only eight years from Qin Shihuang's death to the establishment of the Han Dynasty.
