China's diverse landscapes and breathtaking natural wonders have long been a big draw for travellers and adventure-seekers. From the majestic Great Wall to the Terracotta Army, each destination offers a unique experience. One such fascinating spot is the Qiantang River, popular for its extraordinary phenomenon of flowing backwards from the sea. Despite how bizarre it may seem, the rare natural occurrence is very real. Known as a tidal bore, it is found in a few rivers around the world. However, the most dramatic example of this occurs in China's Qiantang River, located in Zhejiang province.

A tidal bore is formed when incoming sea tides reverse the flow of a river or small bay. The water body must have certain requirements for this phenomenon to occur. The river must be shallow, the mouth flowing into the sea must be small, and the bay must be shaped like a funnel. The other crucial component of the process is tidal variations, typically greater than six meters. The funnel form amplifies the force of the tide, resulting in abrupt rises in water levels and the creation of enormous waves that rush upstream.

Tidal waves on the Qiantang River in Hangzhou may reach heights of 30 feet and surge ahead at the speed of forty kilometres per hour. The thunderous boom of the waves is audible hours before they arrive. Water levels stay high for several hours even after the surge passes. This natural wonder is known locally as the "Silver Dragon." It occurs every full moon but is at its most dramatic during autumn. People assemble along the riverbanks to watch the phenomenon with a large crowd. This breathtaking sight is celebrated with a centuries-old festival that draws around 1,70,000 tourists every year.
