How bad was the wordt flood?

Answer 1

The worst flood in history is often considered to be the 1931 China floods, which resulted in the deaths of an estimated 1 to 4 million people and displaced millions more. The Yangtze, Huai, and Yellow Rivers overflowed due to excessive rainfall and snowmelt, leading to widespread destruction across several provinces. The scale of the disaster was exacerbated by poor infrastructure and inadequate preparedness. This catastrophic event remains a significant point of reference for flood disasters globally.
