Tidal bores surge in Qiantang River in Hangzhou(1/3)

The tidal bores fell on the Autumn Equinox this year, when the gravitational pull from the sun and the moon aligned and peaked to make the tides powerful. The narrow flared-shaped estuary and straight riverbed provides geological conditions for the spectacular scenery of Yixianchao (a thread breadth to the tide).
