why is the Huang he river, despite being an important water source for the ancient Chinese, sometimes called china's sorrow

The Huang He River is sometimes called "China's Sorrow" because of its propensity for devastating floods. The river has a long history of overflowing its banks and causing widespread destruction and loss of life. These floods have been a recurring problem throughout Chinese history, with some of the most destructive floods occurring in the 19th and 20th centuries. The river's geographical features, including its flat and low-lying floodplain, make it prone to flooding during periods of heavy rainfall or rapid snowmelt. As a result, the Huang He River has brought both prosperity and devastation to the people who depend on it for water and irrigation.
