The dutiful son wants to shout: Southwest Road. This is a custom in folk funeral culture. As for why it is southwest, we should start with ancient culture. In ancient times, there was a saying that "the land is full, the heaven and the earth are divided into four roads, the southwest is God, the southeast is Bird Road, the northwest is Animal Road, and the northeast is Ghost Road". According to my grandfather's legend, the Buddha lives in the southwest, which is the so-called west. That's why Tang Priest took pains to find the true scriptures in Tianzhu, southwest China. After a mortal dies, the public wants the deceased to die. This man is interested in the relatives of the deceased, and he tries to know the way for the deceased. "

From this sentence, we can know that, because the southwest represents the direction of God, if we go to the southwest, then people's souls will go straight to heaven, because in the traditional thinking of China people, we all hope that people will go to heaven after death, instead of going to the underworld, which also fits why the direction of Tang Priest in The Journey to the West is the west, and the west is the celestial world, which is often said as the western paradise.

And why are you yelling? Because in China people's culture, people have three souls and seven spirits. After death, three souls and seven spirits will leave the body, and calling is the way. Therefore, there is a saying: "Anyone who is depressed and in a state of soul is not allowed to walk. Therefore, for the living, his son thought it meant. Judging from the funeral ceremony, after death, people are in a trance and use old clothes to attract their souls. The eldest son of the deceased covered himself with the clothes of death. The old clothes were worn for a living, stained with the skin of the deceased, and possessed himself with anger.

It means that after death, the soul is in a state of chaos. If you don't guide them, you will be displaced and become a ghost, and there is no way to reincarnate. At this time, relatives are needed to lead its soul and guide its direction. This tradition still exists in some places and can be seen in some film and television works. For example, there is a scene called Lu in Red Sorghum, which was very common in Shandong at that time.
