What is Dragon and Tiger Sand (Mountain)?

Qinglong and Baihu are a pair of yin and yang. There will be many dragon, tiger and sand hands in the upper structure of the cave, which was described as "jagged teeth" in ancient times. The ridge of Longhu Mountain, which protects the cave, should be perfect and symmetrical, not higher than Longdong and not too low, so as to protect Longdong. Qinglong Square represents the concepts of male, power, education and spirit, while Baihufang represents the concepts of female, wealth and material. Experienced feng shui masters can directly see the influence on people from the shape of dragons and tigers.
