Qin Shihuang (reigned from 259 to 2 10) was the first emperor in the history of China to practice centralization. He strengthened centralization through a series of reforms and unified writing, roads, weights and measures, etc. He also pays attention to the development of culture and education, such as popularizing Chinese characters, unified measurement and strengthening military forces. However, he also has a ruthless side. He controlled the people by burning books and burying Confucianism, built the Great Wall, and even spent a lot of manpower and material resources when building terracotta warriors and horses on a large scale, which caused people's livelihood to be overwhelmed.
Emperor Wu of the Han Dynasty (reigned for 156 to 87 years ago) was one of the most pioneering emperors in the history of China. He carried out a series of pioneering policies, such as exploring the Silk Road, developing the western regions and pacifying the Xiongnu. He handled government affairs with a pragmatic attitude, attached importance to the development of culture and education, advocated Confucianism, prospered culture and art, and popularized traditional cultures such as medical skills and divination. His pioneering spirit and rich cultural background laid the foundation for the later Han Dynasty.
Generally speaking, Qin Shihuang and Han Wudi were both outstanding emperors in the history of China, and their respective ideas and policies of governing the country had a far-reaching impact on the history of China. However, their ruling styles and personalities are also different, which need to be understood and evaluated according to the specific historical background.
