This historical story is not a story about good guys and bad guys. It is the story of a lonely man who wanted to be ahead of the times, but was eventually crushed by the times. The path he left behind is walked by future generations; the shovel he used to dig the river is used by future generations to fill in the soil. The merit is his, and the fault is also his, but the road has become the road for everyone. "In the fourteenth year of the Great Cause (618), Emperor Yang of the Sui Dynasty was killed in Jiangdu. Twenty-two years later, Emperor Taizong Li Shimin of the Tang Dynasty perfected the imperial examination, dredged the canal, opened up the Western Regions, and pacified the Turks. History books call it: "The Rule of Zhenguan". And the canal that runs through China is still called the Sui-Tang Grand Canal.
