The Qiantang River in China unleashes one of the world's three greatest tidal bore spectacles. Have you ever witnessed any of its unique patterns—the net-shaped tide, fish-scale tide, cross tide, colliding tide, butterfly tide, or ripple tide? Each year, from the 15th to the 18th day of the eighth month in the lunar calendar, the river roars to life, entering its prime viewing season. During this time, towering waves driven by the surge can rise several meters high—an awe-inspiring natural wonder.
