Qiantang River

Located in Zhejiang Province, China, it finally flows into the East China Sea. The tidal current of its estuary is Qiantang River, which is famous all over the world. Every year, many tourists come to watch this spectacle.

Before the tide came, a small white spot appeared in the distance, which turned into a ray of silver line in the blink of an eye, and the white line rolled in with the low tide sound. Almost before people can react, the surging tide has roared, with a peak of 3-5 meters. The back wave catches up with the front wave, layer by layer, like a long leucorrhea, overwhelming.

As the poem says: "Qiantang looks at the waves and suddenly becomes outrageous." It seems that in ordinary rivers, the energy is amazing. " From far and near, the tide rushes in, pushed by the tide, and the sound is like thunder, and the beads are splashed with jade. It is Malik's 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. In May 2020, it was selected as the first batch of "Zhejiang Cultural Imprint" list.
