Translate geomantic omen

Draw water. The upper left corner is the incoming water, which is divided into two branches by pointed sand ("sand" simply means the land or mountains around the cave), which is called the pattern of "fighting water", and there is a fierce disaster in building tombs and houses. It is easy to cause the death of future generations. Whenever water (and sand) comes into contact with rapids, children and grandchildren will kill each other and die, and children and grandchildren are prone to disability.
