Guishanding is the tip of the needle against the wheat awn, that is, the gold is divided with the amber and the boxer. This means that dragons, water and sand should be considered together when orienting. It is said that after considering these factors comprehensively, this is a better position. However, it should be noted that whether the needle direction is consistent and correct depends on the dragon, which is the key to ensure the cooperation between dragon, water and sand.

It is necessary to determine a better scheme according to the comprehensive factors such as dragon, water and sand. Therefore, it is suggested that professional geomancers should be required to make orientation and selection according to the actual situation during the specific operation.
