China observed a natural phenomenon on the Qiantang River

This year, a unique natural phenomenon – a tidal wave on the Chinese river Qiantang – coincided with the Mid-Autumn Festival, which takes place in China and Hong Kong on the eve of the first full moon of the eighth month of the lunar calendar.

Thousands of people gathered in Hainin City, Zhejiang Province, to see how millions of cubic meters of seawater are moving against the current of the river, skirting small islets, then breaking up into a local dam. The wave travels up to 55 kilometers and sometimes reaches 9 meters in height.
