Qiantang River Bridge is located in the south of West Lake in Hangzhou City. It was designed by Mao Yisheng, a famous bridge expert in China. It is also the first double-deck railway and highway bridge built by ourselves. It crosses the Qiantang River. Therefore, the origin of Qiantang River is noble. I walked all the way from Longjing Village in West Lake to Qiantang River Bridge along the eighteen streams of Jiuxi River. I was deeply shocked when I saw him at the first sight. Qiantang River Bridge has a history of more than 70 years. So far, there are no safety problems. It is a miracle. The Qiantang River tide is civilized because of Lu Xun's articles, and the Qiantang River Bridge, as a direct bearing of the Qiantang River tide, has to be lamented. Qiantang River Bridge itself also has a moving story. After the bridge was built, the outbreak of the War of Resistance Against Japan was led by Mao Yisheng, the designer, who blew up the bridge. It was only in 1946 after the victory of the War of Resistance that the bridge was repaired, so it also has special historical significance.
