The wedding car goes back and forth as a turning point, not taking a turning point means not taking the same path, not taking a repetitive path. There is no turning back within the community, just don't take the same road as when you go back from outside the community to your home. I believe this can be easily achieved. The route for marrying the bride and returning to the new house cannot have duplicate sections, as going back implies that divorce will not be long, which is a major taboo.
The wedding car does not turn back refers to the fact that during the wedding car's journey, whether it is picking up the bride or returning to the groom's house, there must be no repeated sections of the road, otherwise it is turning back and carries the meaning of divorce. Therefore, this cannot occur during the wedding car's pick-up. Many newcomers place great emphasis on the word 'shun', which means smooth sailing. Therefore, when choosing a path, they tend to use a clockwise direction. Whether it is clockwise or not, the choice should be based on traffic conditions.
