Qiantang River is the biggest in Zhejiang Province, running from the west to Hangzhou Bay in the east. The extraordinary surging tide of the River is a world-renowned natural wonder caused by the gravitational pull of the stars and planets. The centrifugal force produced by the rotation of the earth and by the peculiar bottleneck shape of Hangzhou Bay makes it easy for the tide to come in, but difficult for it to ebb. The soaring tide of the Qiantang River is such an amazing spectacle, that only the Amazon River's surging tide can compete it!
To witness this awesome sight, hundreds of thousands of Chinese people come to the annual Wave Watching Festival in Hangzhou. In terms of its history, the custom of watching the bore tide has happened for more than 2000 years. It first appeared during the first century.
