The Qiantang River Bridge is located in Hangzhou City, Zhejiang Province, and it is the first double-decker bridge designed and built by China itself.
Qiantang River Bridge is located in Hangzhou City, Zhejiang Province, China, it is the first double-decker bridge designed and built by China itself, and it is designed by Mao Yisheng, a famous bridge expert in China.
Legend has it that when Mao Yisheng was young, his hometown held a dragon boat race during the Dragon Boat Festival, which attracted a lot of people to compete on the bridge, and as a result, the bridge collapsed because it could not bear the weight of too many people, causing a lot of casualties.
This incident made the young Mao Yisheng decide to build the world's most difficult bridge, and since then observing the bridge and collecting bridge articles have become a part of Mao Yisheng's life, and later he also participated in the design of the Wuhan Yangtze River Bridge.
