Located on the border between northwest China's Shaanxi Province and north China's Shanxi Province, the Yellow River, China's second-longest river, is like a giant dragon, crawling over a vast stretch of land.

The Hukou Waterfall sits in a narrow, precipitous gorge here and is known for rapid water speeds creating thunderous sounds.

The magnificent waterfalls created clouds of mist and rainbows, attracting flocks of visitors every year.

The breathtaking scene can be viewed in both provinces.
