The Hukou waterfall on the Yellow River has taken on its best look recently as the world's largest yellow waterfall. The waterfall is located at the border between north China's Shanxi and Shaanxi provinces. The waterfall's water volume usually increases greatly between late August and early October, giving the visitors its best view, thanks to rising rainfall and water diversion along the upstream of the Yellow River. Since this autumn, the water volume has been over 1,600 cubic meters per second. The 300-meter-long waterfall group is attracting more and more tourists and photographers.
