It can be found in the books recorded in ancient tomb raiding that why the partners of tomb raiding are often uncles, so what's the significance?

First of all, in ancient times, the punishment for robbing a tomb was very heavy. Grave robbers are basically caught by the government and live to die. In ancient times, there were only a limited number of men in each family. In order to prevent this from happening forever, father and son are usually not allowed to rob the tomb together, otherwise once caught by the government, both father and son will die at the same time, which will do too much harm to a family. If it is a combination of uncles and nephews, each family will only lose one male, and there is still a chance to thrive.

Secondly, grave robbery is an extremely dangerous activity, which tests the skills of grave robbers and their trust in their companions. Therefore, grave robbers are often handed down from one family to another, and grave robbers gangs basically do not consider the participation of outsiders. After all, well-informed companions are more trustworthy and trustworthy, so it will not happen that they are framed because of uneven distribution of benefits, nor will it happen in self-destruction.

However, grave robbers need trust and cooperation, as well as reason and calmness. When encountering an irresistible sudden disaster, you can't be emotional, and the affection between uncle and nephew is just right, neither losing your reputation nor being impulsive, thus avoiding the stability of the grave robbers. If the father and son go into battle, there may be situations in which one person is saved and one life is saved.

The last reason is that uncle and nephew's homonyms are "saving" and "living". For good luck, it is not uncommon for uncle and nephew to play together. After all, grave robbery not only considers technology, but more importantly, luck. In ancient times, wealth was associated with geomantic omen. Grave robbers are naturally more superstitious about feng shui luck and are willing to believe that "uncle" and "nephew" are a little small.
