First, although the coffin is heavy, if the coffin rope can be worn off, it should be that the coffin has too sharp edges and corners, and there will definitely be casualties if the coffin falls. Generally, the ropes used to carry coffins are very particular, and the bearing capacity is definitely good. If it is suddenly broken, it may be that the edges and corners of the coffin are not polished smoothly, and the rope is interrupted in this process. In this case, the coffin carrier and the funeral procession may be hit by coffins, not to mention most of the burial? Up the hill? When you are buried underground, you are more likely to get injured when going uphill. This is the case in the team that was injured by the coffin in Yunnan.
Second, revenge? Coffin ropes are mostly nylon ropes, which are generally more wear-resistant. If they are broken, someone may have touched them. In rural areas, there are also many places where there is friction. The coffin bearer or funeral director may have offended someone and just entered the funeral director. If one of them prepares a rope that will break in advance, it may hurt the coffin bearer or the funeral director, but it is just an accident for ordinary people. Some people may say that it is obvious to cut the rope, and people will definitely see it. Do you believe me? In this world, there are no fewer than ten ways to break a rope and make it invisible.
Third, the dark side: the coffin is overweight, and there may be more than one person inside. Another scientific theory is that the coffin is too heavy. With our respect for the dead, no one will open the coffin after it is sealed, so if you want to hide something in the coffin, few people may think that this house is just an accident, but there are Tibetans, corpses and cultural relics in it.
Generally speaking, there are several scientific predictions about the broken coffin rope, but in superstitious customs, no matter what the prediction is, the outcome is the same anyway, that is, don't bury it that day, find another time to pick the mountain.
