The tidal bore in Qiantang River is one of the three largest tidal bore in the world, which is caused by the centrifugal effect of celestial gravity and the earth's rotation, as well as the special topography of the bell mouth of Hangzhou Bay. Yu Yafei said in his poem: "Qiantang looks at the waves and suddenly becomes outrageous;" It seems that in ordinary rivers, the energy can be amazing. "
At the beginning of the tidal wave, a white line flashed on the river, accompanied by rumbling. The tide surges from far to near, and it sings like thunder. In an instant, the tidal bore raised a water wall three or four meters high and stood upright on the river, spraying beads and splashing jade. This is Malik Pentium. Tide watching began in Han and Wei Dynasties and flourished in Tang and Song Dynasties. After more than two thousand years, it has become a local custom.
