So all we have to go by are a few photographs of the natives and some very bizarre rumors. Although the condition was officially recorded in 1951, reports of dwarf sightings date as far back as 1911. In 1947, English scientist Dr. Karyl Robin Evans claimed to have seen a few hundred dwarfs living in a remote valley, in the area where Yangsi is located.
Naturally, the villagers began to believe that evil forces were at work. Some blamed the bad feng shui of the area, while others thought it was because their ancestors were not given a better burial.
But the most bizarre explanation so far states that a long time ago, a man named Wang spotted a black turtle with strange feet. Some of the villagers wanted to let it go, but they ended up roasting and eating it. When the disease struck, they started to believe that they might have been better off releasing the turtle.
Some people blame toxic gases from when the Japanese invaded China many years ago. But the Japanese never reached the village of Yangsi, a fact that the villagers are not willing to accept.
Throughout the years, several residents have left the region in fear of being affected by the strange condition, but things seem to be improving. While many of the older locals are up to 80 centimeters in height, the new generation seems to be unaffected by the weird dwarfism phenomenon.
