Twins are a special physiological phenomenon in human reproduction. Scientific research shows that the natural occurrence rate of the population is about one thousandth, but in Mojiang County, Yunnan Province, especially in Hexi Village, the proportion of twins far exceeds 4%.
According to incomplete statistics, there are 1200 twins in Mojiang County. Black goats can have twins. The chickens and ducks raised at home lay double yellow eggs, a banana tree bears two bunches of banana fruits and two banana flowers, and a lotus bears two flowers.
It is understood that there are only 380,000 people in Mojiang County. How can there be so many twins? Locals say there are two reasons. One is that the Tropic of Cancer passes through here wonderfully, and twins will be born after sleeping in a twin bed across the Tropic of Cancer. Second, there is a twin well, and drinking water from the well will also give birth to twins.
Known as Shenjing, this double well is located in Hexi Village, about 3 kilometers west of Mojiang County. There are two wells, one for living and the other for drinking water. Well water is full of clear, sweet and delicious all year round. The local people said that drinking water from the twin wells gave birth to twins, and many couples from other places gave birth to twins soon after drinking water from the twin wells. Therefore, young couples who come here will take a pious sip of well water, thinking that if they drink this water, they may be pregnant with twins.
