Hukou Waterfall of the Yellow River is divided into Shanxi and Shaanxi two scenic spots. It is on the east and west sides of Hukou Waterfall. I went to the scenic spot of Shaanxi three years ago. In May and August this year, I went to the scenic spot on the Shanxi side. Hukou Waterfall is a special waterfall caused by the changes of the Yellow River, more than 400 meters wide of the river, to the Hukou only 30-50 meters wide, and the gap of about 30 meters, forming a waterfall, like a giant pot, the water of the Yellow River, so called the pot mouth. Hukou waterfall is extremely spectacular, rapids, splashing foam forming smoke, and sonic earthquakes for several miles. When I went in May, the Yellow River water was clear, and the water in August was yellow. The "clear waterfall" and "yellow waterfall" were different due to the time to watch, and there was a completely different. Of course, by the comparison of photos, it can be seen that the water flow of the "clear waterfall" is much less than the "yellow waterfall". Tickets for both scenic spots on both sides of the Straits are 90 yuan, and you have to reach the viewing attractions through Jingjiao Car. The Jingjiao Car in Shanxi is closer, and the Jingjiao Car in Shaanxi is farther away. Looking at the Hukou Waterfall of the Yellow River is to see the waterfall, droplets, and the waterfalls formed by the wide and narrow bands of the Yellow River. The shock brought by the water mist, this shock is given by nature through the Yellow River, it is worth seeing.
