San Diu

The San Diu migrated to northern Vietnam from southern China in the late 1600s and are currently living in seven different provinces. They gather water daily from streams rather than digging wells because they believe that spirits live in the earth and if they dig a well they will hit the veins of a dragon. They live in constant fear of offending the spirits that they worship. Please pray that the San Diu will come to know the Prince of Peace who loves them deeply.
