The Hukou waterfall, the largest yellow waterfall in the world, has embraced its first spring flood of 2020 as snow and ice on the upper reaches have melted away. The flood usually happens between March and April from the Yellow River section in Inner Mongolia Autonomous Region. When the currents reach the lower reaches around Hukou Waterfall, they run past blossoming peach flowers. The spring flood at Hukou Waterfall is also named as "peach blossom flood."
