When I saw the famous Beijing-Hangzhou Grand Canal on the spot, I was deeply shocked by its momentum. The real Grand Canal is much broader than you can see in pictures and books. It is said that Emperor Yangdi of the Sui Dynasty built the Grand Canal to let himself go to Yangzhou to see Qionghua, which was totally the blackening and vilification of Emperor Yangdi of the Tang Dynasty, as long as a little brainstorming, it would be impossible. Seeing the Grand Canal, he had to be convinced by Emperor Yangdi's long-sighted strategic vision and courage. Emperor Yangdi of the Sui Dynasty was still in love with the Grand Canal before his death, which shows that he knows the great significance of the Grand Canal for China's development. I personally came to the scene to see the Grand Canal and had a glimpse of why Emperor Yangdi of the Sui Dynasty had to build the Grand Canal. The Beijing-Hangzhou Grand Canal is worthy of its merits in the contemporary era and benefits for thousands of years.
