Han Wangxi, nearly 70 years old, has spent months digging a five- to six-meter-deep hole in the riverbank of Moba Gorge in Longnan, China, searching for gold. He carefully sifts sand from the rock and washes it repeatedly, hoping to find even tiny pieces of gold. On good days, he finds gold the size of a needle, but on bad days, he finds nothing. Despite his struggles, he remains convinced that gold lies beneath the clear water. However, he is worried about losing his home when a reservoir is built in the area.
