It is unlucky to scold others at their doorstep.

In the traditional culture of China, being scolded at home is regarded as an act of destroying family harmony, which may affect family fortune and geomantic omen. According to Feng Shui, doorways are the entrance of family and wealth. If something bad happens at the door, such as being scolded, or being attacked by discordant words, it may break the feng shui pattern at home and affect the fortune at home.

However, there is no clear scientific basis for the statement that what will lead to bad luck. Traditionally, people generally believe that insulting and cursing others will bring bad energy and affect the fortune of themselves and others. However, these claims have not been scientifically confirmed.

Generally speaking, in China society, we should respect each other, keep friendly words and deeds, and avoid causing adverse consequences to ourselves and others because of swearing.
