#Record my life#I thought the Beijing-Hangzhou Grand Canal should be very wide. Who knew that the ancient Grand Canal I saw in Guazhou Gudu today would be so narrow! I visually measured that the span of the canal would not exceed 50 meters. Because the Guazhou Ancient Ferry Port has now become a water conservancy project with bridges and gates. This sluice consists of three holes. Only 8 meters per hole. This means that a 24-metre gate can hold the canal's locks!

Think about it. That's how it should be. After all, the canal was dug by man. If you dig too wide, how much manpower and material resources do you need?
