It is illegal to rob a tomb. Grave robbers robbed ancient tombs for their own benefit without the permission of the state. It has led to the loss of a large number of ancient cultural relics, and our archaeologists and historians cannot fully understand a period of history.
Yao Yuzhong has a strong learning ability. Because of the poor conditions at home, he doesn't read much. He mastered the knowledge of astronomical phenomena and geomantic omen through his own study. After learning Feng Shui, he can know which places are suitable for cemeteries. It was through the knowledge of geomantic omen that ancient aristocrats searched for graves.
Yao Yuzhong also studied the local customs and burial culture so that he could judge the exact location of the cemetery more clearly. Yao Yuzhong has been robbing tombs for 30 years. He was in the dominant position at that time. Because they don't know the local situation, grave robbers from other places fail every time. But he can not only accurately judge the location of the ancient tomb, but also judge the accurate information such as the funerary objects, the preciousness of the funerary objects and the identity of the tomb owner.
Every time Yao Yuzhong went up the mountain to look for the cemetery by himself, after determining the location, he also finished the later excavation work by himself. So almost no one knows his habit and process of grave robbery, which is why he has been at large for more than 30 years and has only been arrested so far.
The ancient tomb is a powerful evidence left by history for us to explore the answer. With these ancient tombs and collections, we can learn about our history and our ancestors. It is illegal for grave robbers to steal and sell cultural relics for personal gain. I think if Yao Yuzhong does the right thing with his learning ability, I believe he will do something else.
