Qiantang River Tidal Bore is an important scenic spot of Qiantang River. Generally, around August 15, Lunar Calendar is the best time to observe the tides. At that time, the largest Qiantang river tidal bore can be several meters. Before the arrival of the sea tide, a tiny white dot appeared in the distance, which turned into a silver thread in a blink of an eye. Later on, accompanied by waves of dull thunder, the white line rolled to the sea. In ancient Hangzhou, Phoenix mountain, Jianggan area were the best place to watch. Due to the change of geographical location, from the Ming dynasty, Haining, Hanguan was the first resort for tide observation, so it was also called "Haining Tidal Bore".
