What is the significance of spring eye in geomantic omen?

Spring eye: the source of spring water.

Spring is the place where groundwater naturally gushes out of the surface, or where the aquifer gushes out of the surface. According to the different flow conditions, it can be divided into geysers and regular springs. If there is no obvious water flow after groundwater emerges from the surface, it is called seepage. According to the temperature of water flow, spring water can be divided into hot spring and cold spring. Spring water can be divided into eight grades according to its flow. The flow rate of the primary spring exceeds 65,438+000 cubic feet (2,800 liters) per second, the flow rate of the secondary spring ranges from 65,438+00 to 65,438+000 cubic feet per second, and the flow rate of the eighth spring is less than 65,438+0 pints per minute (8 ml per second).
