Who is the greatest emperor in China in the eyes of westerners? What achievements did he make during his administration?

Westerners think that the greatest emperor in China is not the familiar Qin Shihuang, Han Wudi and Emperor Taizong, but the pioneer of the Sui Dynasty-Emperor Wendi. During the reign of Emperor Wendi of Sui Dynasty, many policies were formulated, which had a great influence on later generations of China.

Now when people mention the Sui Dynasty, they may be more impressed by the absurdity and arrogance of Emperor Yang Di, but basically no one remembers the achievements of Emperor Wen. Historically, the Sui Dynasty was very similar to the former Qin Dynasty that unified China, except that the whole dynasty completely collapsed after only two emperors came to power. But in fact, Emperor Wendi of Sui Dynasty had no less influence on China's later generations than Qin Shihuang. It was only because the later Tang Dynasty belittled the Sui Dynasty that people followed suit and belittled the Sui Dynasty all the time, which led to the unknown achievements of the Sui Dynasty.

Since the Han Dynasty, the Central Plains of China has been in a state of war, but the rise of Emperor Wendi in the war here ended the war in the Central Plains and completed the reunification of China after Qin Shihuang. In the dynasties after China, China mostly maintained the unification established by Emperor Wen of Sui Dynasty. After Emperor Wendi of Sui Dynasty unified the Central Plains, he abandoned the previous county system and founded the predecessor of the three provinces and six departments system. At that time, it also inherited the system established by Emperor Wen of the Tang Dynasty, but only modified some places according to the actual situation.

Later, Emperor Wendi of Sui Dynasty established the imperial examination system, which enabled outstanding talents to be selected. This system has been used in China until now, and even the college entrance examination now has the shadow of the imperial examination system. Even many western countries marvel at the imperial examination system and introduce it into their own countries. Legally, Huang Kai Law revised by Emperor Wendi of Sui Dynasty changed those cruel laws before China, and was also quoted and inherited by the Tang Dynasty, which had a great influence on later generations.
