How it's used

This term is a direct translation of the psychological condition and is primarily used in formal or academic contexts rather than casual conversation. Most people in Hong Kong are more familiar with the cultural superstition surrounding the number four, which sounds like the word for death, rather than the Western fear of thirteen. If you need to explain this concept to locals, you will likely need to clarify that it is a Western cultural phenomenon.
