This is actually a general description of the topographic structure of ancient cemeteries, and it is also the experience summarized by many people through historical discoveries. This is also a typical funeral custom in the Han Dynasty, which has been influencing since the Han Dynasty.
So why is there such a statement? Generally speaking, mountains are ups and downs, high and low. In ancient times, it was usually called Long Mai. The ancients thought that the ups and downs of mountains were actually the movements of Long Mai's Qi. The highest part of the mountain is the place with the strongest atmosphere.
Most tombs in the Spring and Autumn Period, Warring States Period and Western Han Dynasty were buried at or near the top of the mountain. But it was later found that the top of the mountain was not suitable for the location of the cemetery. The reason is that although the auspicious spirit is the strongest and the gas field is the strongest on the top of the mountain, if the deceased is buried on the top of the mountain, it is like a person standing on a bare hill and exposed to the sun, rain and dew, it is easy to attract the risk of lightning strike. At the same time, it will also indicate that future generations will be punished.
Therefore, most tombs from the Eastern Han Dynasty to the Wei, Jin, Southern and Northern Dynasties were dug halfway up the mountain. The tombs of Sui, Tang and Song Dynasties are generally buried under the slopes. According to Feng Shui, burying a mountainside is like being in a mother's swaddling clothes. Surrounded by mountains, it has won the favor of nature. The dragon soul also goes from the mountain to the foot of the mountain, and the dragon soul above can be better absorbed below.
According to the above principles and statements, grave robbers have a lot of knowledge about the customs and habits of different times, different nationalities and different nationalities, so they have also summarized many such experiences for guidance, and therefore many experts have appeared. They are familiar with a lot of common sense and know where there are graves and treasures. This skill is also very admirable. Many people worship them as teachers and hope to make a fortune with them.
In fact, the location of our graves in each period is very different, and future generations have found experience for future generations through hard practice. Emperors of past dynasties were very particular about the place where they chose to be buried after death. Generally, it is a place with good feng shui, such as a hillside, and each era is different.
They had a lot of wealth before their death, which they could never use up, so they chose to put it together after their death, as if they had taken it away. Some people's tombs after death also show their identity and are beautifully built, which has aroused many people's covet.
Of course, they are also afraid of being taken away by others, so they will set up many organs to protect their property after death. Some took all the air inside, and those who went in lost their lives because there was no protection. Some are worse than this. With defense, people will inevitably find ways to deal with it. Although the minds of predecessors are fierce, they can't stop the wisdom of future generations. They have found many ways to crack it and successfully stole many treasures.
