Why can't you step on the threshold?

The reasons for not stepping on the threshold are as follows:

1, some places think that the threshold is the neck of the ancestors, and you can't step on it, otherwise it is disrespectful.

2. Stepping on the threshold will ruin your feng shui and collide with your family god (in some areas, folklore thinks that every family has a patron saint).

3, the threshold is the neck of the family, not the head of the family, so there is a saying: avoid stepping on the threshold, avoid sitting.
