During the Mid-Autumn Festival, you can see many people burning paper at the crossroads. Why burn paper at the crossroads?
For example, some are sent, usually at the intersection. This is because some people in the family are unhappy, possessed by evil spirits or sick. As for the family, they arranged some sacrificial paper money, came to the intersection to worship, and then burned the paper money. Is to send away things with bad pathogens.
Choose at the crossroads, you can send it further and extend in all directions. Bad things, after delivery, are convenient to leave. And it's not easy to come back. If you do it again, it's easy to get lost at the crossroads.
The other is that we don't know where people come from, so if we are at the intersection, it's easy to get beaten up and then please go. How people go back depends on themselves.
Another is to invite people (evil spirits) out for dinner. Of course, we don't want to entertain guests in our own home or at the door. Otherwise, people will not leave because they are full of food and drink. What shall we do or walk around the house? What shall we do?
So please stay away, it's most appropriate, and it's at the crossroads, and then people leave, so it's more convenient to walk.
I explain this in a more popular way, which is not so mysterious and can be understood at a glance.
There is also a saying that there is no tomb worship, and unborn children should be at the crossroads in order to get the money and things burned to them. There are also many ghosts who have not been sacrificed, so there is also a saying that burning at crossroads is also a good thing.
